Installing basic plumbing in my place and would appreciate a little advice :D

Seems simple enough after watching some videos but I thought I'd run it by you folks to see if you had any tips or thoughts.
The only running water I have atm is an outdoor yard hydrant fed by a private well. My plan was to dig the yard hydrant up, replace the L fitting with a T fitting so I can run PVC underground into the house, and then it needs to go aboveground outdoors because I live on the second story, the ground floor is just an open garage/shop.
So I imagine I'll want to insulate that exposed outdoor pipe well. I was wondering if I could rig up something similar to a frost free yard hydrant, a hole thats underground so that the pipe would drain out whenever I had the water off, so the outdoor pipe would be empty and therefore not freeze. What would you recommend to solve that issue?
Then from there I'm just running pipe inside so it can feed a sink, and ideally I'll also run it to a tankless water heater so I can finally install a proper shower here. How to run hot water pipe out of the water heater is where I start to get confused; like can I feed my shower exclusively with a hot water pipe or must it be both a hot and cold water pipe? Since its tankless and I can just set the temp digitally I imagine I only need one hot water pipe for the shower.
So, I guess I'd run the hot water out of the heater to a T fitting, one branch feeding the shower and one feeding the sink. Finally I can do dishes inside and shower! Haza!
Random questions I have are: Sink drain pipes; since I'm not connected to city sewer or anything I'm just going to be draining it into the ground. Are there any additional parts you add the exterior drain pipes to prevent cold air from coming into the house?
I'll probably also want to install a filter somewhere along the line since its well water. Maybe right before the water heater would be a nice easily accessible spot?
Was also planning to install the water heater myself if anyone has tips or warnings on that. The videos make it look easy enough, I know an electrician who can help me with the electrical aspects of it.

I get where you are going with the drain hole in the pipe, but you would have to have a shut before the hole or it will be squirting water out all the time. I would run it inside the garage and insulate where it elbows up and in. You can also sleeve the water pipe, say you are running 3/4", put it inside a 2" pipe (any pipe will work for the sleeve) drill holes all over and fill it with spray foam. I run a small LP on demand water heater, yes you can just run the hot to shower but the temp coming out is dependent on time of year (summer/winter) and dependent on the air temp. This is my experience with the LP style heater, I would think the electric style would be more stable. I have installed a lot of the electric ones and there are no dials for summer/winter or a vent pipe either. For the grey water from sink, you need a P trap under the sink which will always have a little water in it to prevent smell from coming in and will keep air from coming in in you're case. We run grey water also.

If you are in Wisconsin the pipe needs more insulation than here in West Virginia. I use those swim noodles you can buy for @ $1 in the summer.

Yeah if you don't mind turning on both hydrants to get the water flowing then make another trip to turn them both off. Of course if you install that T then the first hydrant won't shut off the flow, so the second hydrant would have to be in a pit that you could uncover to access it.
Edit: I got that wrong, I don't think they second hydrant would have to be in a pit.

Many thanks for the replies folks.

Right. I was hoping some sort of hardware existed that could clog/unclog the hole. The winters aren't too bad here so maybe I can just insulate it real good and/or keep the water running at a trickle when its real cold.

That makes things simpler, hurray. Mine would be electric. Those tankless water heaters look pretty easy to install in the videos. I had an acquaintance tell me it was a real headache but I can't see what the complication would be. any tips or is it as straightforward as it looks?

ahh that makes sense.
This is all coming together in my head nicely now. I should've done this ages ago.

Ha nice. Maybe i'll get some barbershop style noodles so my pipe can be a bit more decorative

all the electric water heaters i'm looking at only have a 35 degree temperature rise. So does this really mean it can only heat 50 degree groundwater to 85 degrees even if i set the dial at 105? Maybe it gets it hotter if its at a lower flow rate?
Having trouble finding the right keywords to answer this question with google

My On-demand gas heater is a 35 degree rise so I stripped the insulation off an old electric water heater and stood it next to the wood stove so that the water rises to room temperature before entering the On-demand appliance.

Oh right on, I'd been considering something similar. Still pretty lame though, like why don't they design them to be able to cycle water through the heater twice to get to the actual desired temperature or something, i guess that might fuck with the flow. Or run two small water heaters in series. that actually might not be a bad idea, get two of the cheap ones and have one feed the other
bah, i'm annoyed by this. gas isn't an option for me. i wonder if i get one of the pricier ones with higher flow rates that might make a difference in temp
edit: Okay it looks like lower flow rates do result in significantly higher temps. problem solved
