HW vs SW RAID: Kind of a religious question. HW has some advantages when using RAID-5 or RAID-6 (less CPU load). When using RAID-0 or RAID-1 there should not be any difference performance wise. HW RAID gives you some advantages in terms of handling, i.e. hotplugging of discs, nice administration console, RAID-10 during install ;-), etc. It's up to you to decide whether it is worth the money. Plus you need to find a controller that is well supported in Linux.
Hardware raid that comes with bbu write caches normally have a speed boost in addition to the extra data safety too.
P.p.s. Creating one swap partition on each disc is correct, because swapping to RAID-0 is useless. Only if you decide to use RAID-1 for the whole disc you should also swap to RAID-1.
creating one swap partition on each disc is equivalent to swapping to raid 0...linux automatically strips/spreads swap data to all available swap areas.
