All I know is a pretty lowcost workflow (note I haven't made a game yet :P):
Wings3D - Object modeling (free - http://www.wings3d.com/)
Ultimate Unwrap - unwrapping models (unwrapping is basically telling where parts of a texture go) this also functions VERY well as a converter betweeen 63 model formats ($40 http://www.unwrap3d.com/).
Gimp - Texturing (free - http://www.gimp.org/)
Lightmap - Gile[s] for quality + support (developer is a blitz user) http://www.frecle.net/giles/home.htm - €40. Slim shady for being free :P http://www.melog.ch/slimshady/

Level editers - cartography shop (http://www.leadwerks.com/) , quill (http://shop.idigicon.com/pdetails.asp?id=418), or maplet (free from accounts section)
