As far as topo maps, it's hard to beat National Geographic series state CD's. Get one for the state of WY and you will have access to USGS 7.5 minute quads for the whole state, which you can custom print at various scales. In addition, if you find an area you want to poke around in, you can transfer coordinates to a GPS. You can also plot travel routes to find out how many miles/elevation gain/loss for a particular route. There's really no substitute for the detail of USGS quads. The detail allows you to find likely areas by looking closely at terrain, escape routes, water sources, etc . . . You can use blm/forest service surface management maps to transfer public/private boundaries. National Geographic also sells "adventure paper" which is more or less water proof and more durable than regular paper. For a given area I will usually print front and back areas I will travelling.
