I have sheetrocked two entire mobile homes in the last 4 years. The first was a 92 Redman that was involved in a flood in 05. Gutted the entire house except for furnace and shower/tub install. Replaced all the insulation, wiring, and plumbing. Sheetrocked the entire house and installed a new subfloor with laminate over the top. Installed all new base and wall cabinets in the kitchen, new appliances, and new toilet. Everything in the house was completely new including the insulation and belly skirt underneath. Of course, we lost the house a year later in a second flood.

We purchased the one that we are in now, a 93 Titan for 10,000. It had been trashed by the family that lived here. So far, we have replaced all the base and wall cabinets in the kitchen, countertops and sink, installed new appliances, laminate flooring in kitchen and living room, new floor tile in second bathroom, new cabinet and sink in second bathroom, completely remodeled one bedroom for our son which included: sheetrock, insulation, flooring, paint, and wiring upgrade, and have wallpapered master bedroom. As you can see by my post, we have extensive experience in remodeling/rebuilding mobile homes. If your house is on a foundation as you say, there should be no problem with installing sheetrock. Just remember to tape the joints to prevent cracking. As for moulding, standard moulding from Lowes or Home Depot will work fine.
