I just got started on DIY myself about a month ago. Well before I ordered my first supplies, I read through the stickies at the top of this forum,
read tons of posts on here, and got a LOT of really helpful advice. I would highly recommend you do a bunch of reading on here before you pull the trigger on your first order. I know it saved me quite a bit of cash on stuff I didn't need that I originally though I would need.

Did I mention reading the stickies? And reading some more?
Oh, and go read the stickies
