If you're creating textures i'd highly recommend using GIMP, it's a free opens source graphics package loosely based on photoshop, you'll need a couple of plugins to export dds, but it works amazingly well..
GIMP:

.dds plugin:

normalmap plugin (for when you start creating textures for 3d models):
https://code.google.com/p/gimp-normalmap/
each of the plugins has a readme file, make sure you read it and follow the installation instructions.

Blender can be a little tricky to get used to, it's control method is very depending on shortcut keys (Num1 for top view, Num3 for right side view, and so forth), but once you get used to that it's pretty easy to use and for a free modelling software is surprisingly comparable to some of the top named 3d software packages.
I highly recommend Unfamilia's blender video tutorial, he takes you through creating a model from scratch in blender, to sing GIMP to create the .dds files and finally to export the final product and import it into GameGuru. He does this very well, explaining everything he does, including what keys he presses and everything. I'm currently going through them one per night (practicing each step a few times before moving on to the next one on the next night) and i'm just starting number 5, so far I've learnt so much in a short time from him, big props to Unfamia, he's da man, he's da J man
Here's a link tot he forum post here that lists his videos.
