uhh...you're not asking for much, are you?..;) Bryce has primitives, and you can model with them using Positive and Negative booleans, though they can't be exported out of Bryce.
Anim8tor will make pretty good props; I think Gerald Day uses it to create his. I use Wings 3d, and it does me fairly well. It's also free (links to both are at the Modeling forum) And you can do basic UVMapping (well others can, I have a mental block or something..;) to get your materials or textures to a model. Or, failing that, you can assign areas for specific materials in Wings, then use ctrl+mouse click to pick the areas and assign them mats in Bryce (which is what I do, mainly)
There are tutorials here at 'rosity to get you started; you can start simple and get as complicated as you want to get. I do believe there's even 2 anim8tor tutorials here, they're for intermediate users, and may gloss over some commands.
Phil C has a tutorial on his site on how to make clothes.
I've done some very limited clothing items (so far, shoes and hats..one-offs that sorta cover up bare heads and feet..;), it's a convenient place to start, since you can maneuver and size the things to fit (unless you're doing stiletto heels..land sakes I have enough trouble with the ready-made ones..;).
there's more coherent answers coming after this post, this should get you started, tho..good luck.

I wish I'd said that.. The Staircase Wit
