I would like to deploy Xen virtualization, however I definately not sure which way to go.
Citrix Xen Server has (AFAIK) better managment tools, but does not provide software raid.
Ubuntu / CentOS has Xen installations and support software RAID.
Is it worth to go and buy HW RAID or just stick with SW RAID and Xen budnled with linux distribution.
Which way would you suggest? Are there any other things I should consider?

I'm running Debian with software RAID1 and LVM as XEN dom0 without any problems for some time now. Installing new domU's couldn't be easier with xen-tools, and plain "xm" gives me all the management power I need. Based on my experience, I suggest you save some money and go software raid + your linux distro of choice.
As for SW raid vs HW raid, there's already a great discussion on serverfault: RAID - software vs. hardware
