Not sure I know any good free uv mapping/texturing vids but Kurt did a couple that I recall for SM.

This model would be pretty straight forward to UV map. (Note UV mapping seems daunting and at first. I found it to be almost unbearable and for the longest time I decided I was going to be a MODELER ONLY because I hated UV's so much, but with time you will find that if you break the task up into smaller tasks and are methodical it will become less frustrating although I find the tedium of UV mapping remains.

(In my case I find that I can UV map farely painlessly now. Unfortunately I realized that now that I can unwrap my models I lack the painting and photoshop and 3d painting tool skills to actually apply textures lol.)

Here is the way I'd attack this model:

1. split it in half
2. separate the leg at the shoulder
3. separate the mandible/tentacle thingies

At this point you are ready to start projecting the maps

4. Planar project the body
5. unwrap and the body and it should be done

6. Planar proj the leg
7. pick an edge up the back of the leg and detach the uv's
8. unwrap the leg and that should be done

For each tentacle / mandible thingy

9. Planar proj
10. pick seam edge on inside edge detach uv's
11. unwrap and they should be done

I'll take a look at it later today.
