Please be more precise on the underlay is part of the carpet.
Is there a moisture barrier on the concrete before ply/ underlay?
How far along are you?
I can resolve your questions but I need more clarifications to get this right for you. I will get right back when you post me back
basic on the conc floor is it should be sealed before any underlay ply. A vaporbarier is needed so ply doesnlt rot. There are panels with dimples that set on the concrete that can be used if you are rich. OR seal the concrete with a dry lock sealer or ploy. The main objective is to keep the ply to concrete dry. Don't glue carpet onto the 1/4 underpayment if concrete is below it. I also will say don't glue carpet in any big areas unless you are a professional. Now in your case it's a sub grade and you don't want to glue the carpet and trap the moisture the moisture into the ply top and the concrete bottom.That will become a vapor barrier to rot ply. Stick with tackles so you can fix the errors OD stretching as you go along. The have carpet strips with masonry nails in them but I recommend getting some Tap Cons for back up in case strip pops when finishing nailing it. Baseboard placement depends on how thick your carpet is thick so it slightly compresses it. Note if padding is separate this gets cut to the tackles strips and not over it like the carpet jute back. The strip locations are out from the baseboard about a 1/2" or enough to just get the carpet chisel in between the strip and baseboard. Again use the kicker an stretcher. By the way you can adjust the "grip" on the carpet. When using a stretcher the fixed part against the wall to push off lay a 2x4 against the installed baseboard to spread out the pressure on the baseboard so you don't crack it while streching the carpet
Hopefully I covered the A to Z here post back if need be
