As far as what one to go for (1 or 2 bar), that depends on what boost you are running/intend to run in the future. Personally I'd get one that reads to 2 bar as it'll cover any future boost hikes. Go for a good quality one though, HKS etc.

Fitting is easy (if you know what you're doing). There have been plenty of threads about boost gauge fitting in the past and I'm sure someone in the technical forums can help as to location of pick up point on the 03 manifold.
