For Organic Modelling (like characters) I find Hexagon 2 to be user friendly, at least since most of the bugs have been ironed out.
It also comes with a decent UV Mapper. Hexagon is free for a limited time only. So grab it whilst you can. Link
Because UV Mapping can confuse people as it's not always easy to figure out where to place the seams, I actually made a video tutorial (but for a different program) explaining how to do it. The same method can be applied to Hexagon's UV Mapper, if it looks odd, just change the projection axis (it'll make sense when you get around to using it): Linky
Then for level design. Seriously, MapScape
is a good program (it was actually made in DBP), it's like 3D World Studio, with fewer features, but completely free. And it's really easy to use. Although MapScape can export to only .x and .dbo (great for DBP!) you can use Lithunwrap to convert it to other file formats. I've used it to convert .x into a .obj and loaded it into my 3D rendering program and Unity3D just fine, just without the lightmaps. The lightmaps will work perfectly in DBPro.
For animation & rigging. MilkShape3D is cheap and export to a large array of formats. Your free (decent) alternatives are TrueSpace or Blender, but Blender's interface is a problem for some people (even though it has improved drastically).
That's pretty much my toolset. I've gone for the 'user friendly' approach, because I don't want to cause myself more effort than necessary.
