Congratulations and many happy turnings.
Hop over to the metal lathe section of IAP that's a good place to start.
What kind of accessories did you get with it?
It probably has an MT2 tail stock, my 7x12 does, so you will need a live center and a drill chuck. The head stock is MT3. Check out CDCO Tools and Little Machine Shop for accessories and cutting tools.
If you are just starting out I recommend Home Shop Machinst magazine. It has a lot of good info on machining and specific articles on mini lathes.
I also recommend getting a small collection of aluminum bar stock, eBay is a good inexpensive source. I have a 5/8" piece that I mount in my chuck and turn a 60 degree angle on it. That gives me a trued up center for between center turning.
