INterior swap

I have a 95 tahoe with blue cloth interior and i was wanting to either get blue leather seats, switch the whole interior with a tan colored leather interior, or i even would like to swap interiors with a tan colored denali of any year but i dont know what that would take. Any suggstions and/or knowledge i should know? Thanks!

Replacing with leather seats is obviously going to be the easiest of the two. However I dont think its going to be cheap either way you decide to go. Check salvadge yards first for carpet, seats, seatbelts, headliner, as for all the plastic trim pieces and dash rather then switching all that out I would buy the automotive interior paint. You can get that at any auto parts store or Wal-Mart. Everything will have to come out to get the carpet and headliner in, except the dash.
Heres a site to check out $194 for the carpet and $539 for leather seat covers http://www.auto-interior.com/
