Use software raid 5 on each disk:
Will this degrade the performance much?
This will increase performance of reads a lot, and degrades write performance a little. As this is a web server you will be doing almost entirely reads.
I've read that software RAID is quite a bit slower than hardware RAID.
The reverse is true in every benchmark I've run. This is because the cpu in your system is easily a x1000 faster than that of a raid controller. In addition raid 5's cpu overhead occurs durning write not reads. (Unless you've lost a drive.)
Also, do I have to use RAID at all?
No, but you asked "How can I best take advantage of the three drives".

Can I not just use each drive separately? (Only asking because I don't know any better. ;) )
Sure put / on one drive, /var on another, and swap on the 3rd.
Or split swap up evenly on all drives, and figure some complex scheme of partitions, and mount to give you use of the the space on
