Welcome to the dark side!

Blender, once you get a little used to it, can be a lot of fun and surprisingly powerful.    Spent most of yesterday playing with the fluid dynamics simulator for the first time.  Ended up making a mini-waterfall

You can export to and from Poser with vertex order preserved so its great for doing morphs.  Ironically I was about to watch some of your tutorials this week on rigging, clothing and doing morphs for Poser.  LOL

Here's some links to some sites with video tutorials

This one in particular is good for showing how to bake hi-poly bump / normal maps to low poly models as well as using Blender to paint textures, sculpt, etc.

And here's a 4 sec video done entirely in blender of the animated water fall I did yesterday using Blender's fluid dynamics.

I think you're going to enjoy using Blender.  I got it initially to help me get started until I could afford to upgrade to 3DS Max or Maya, but at this point I'm not sure I ever will.

Oh, one last tip, go through the Add-ons in User Prefs, there's a bunch of extra's there you may find useful as well.

Happy Blending!
