Take the time to learn Blender. Much much more useful in the long run. Even just the basic. Ignore all the complicated stuff and things you don't need right now. You don't need to animate right away. Get rid of the timeline. Don't feel like learning how to texture? No need to learn about UV unwrapping. Stick with basic materials and colors. Eventually you'll want more than just colors. When you do, Google. Use the internal renderer first. When you feel like you've exhausted it's capabilities it try out Cycles. I still personally prefer the internal one since it's closer to what game engines are like.
