Have I correctly set up partitions for my hard drive?

I am trying to install ubuntu 6.1 on my laptop in addition to windows xp. I am partitioning my 80gb internal hard drive and i would like to know if i have set up partitions correctly:

I believe that i have 2gb for swap, 8gb for root files and 10gb for a home folder for personal files. Should i be setting it up this way, and if so has it been set up correctly?

Also, If possible, I would like to set the windows partition so that files on it can be accessed by both windows xp and ubuntu. I believe that to do this i will need to change
