Installing OpenSusue !?

HI.
This is my first post to this community.

I a new to Linux and i have used Fedora 9 as a live.
I want to install OpesSuse11 but i am stuck when asked for partition.

There is asked for Root and Swap partition and my question is:
1. I want to dual boot. I am using Xp as other OS.
2. Should i make partition prior to installing OpenSuse (partitioning from Xp), if yes then How many partition should I make.
3. While installing SUSE, which partition should be assinged for Root and Swap.

Please Help me understand about this as dap as possible.
