I'm not sure there's any such thing as bad paper these days, just different papers. MGIV is great, MGWT can give nicer blacks but some don't like the creaminess. Kentmere Fineprint is 95% as good and I mostly used that and I'm going to try Foma next. Some papers tone well, some don't.

Get hypo-clear and use it. Wash very well. It's easy to make a carefully-but-insufficiently washed FB print with worse archival properties than a slightly-competently washed RC print. Do like walbergb says with the 2-bath fix; you want complete fixation with absolute minimum time-in-fixer to minimise the amount of thiosulphate absorbed into the paper.

Drying it flat is a bitch. There are lots of threads on APUG to read for techniques.
