Maximizing harddrive space via partitions?

I just installed 10.1. I installed as a dual boot system with XP. I had to manage the partitions a little to do this. I was successful in that I was able to download the 10.1 OS and it works fine. However, I was like a blind bull in a china shop when I did the repartitioning. I know for sure that there is a 512 or so mb partition just out there that i would like to delete. Also I would like to see what is out there for space and simply maximize my disk space since it is not that big, 9.3gb total. Am I able to repartition without jepordy? I am reading up on the partioning stuff but I am having a hard time. I would appreciate any help.

about repartition and since you are in dual boot try partition magic on windows. i think it might be the "easy" way.
