You can use any number of machines. You can make a working
cluster using two. And it can be load balanced. However,
as a beginner, I would recommend using 3 nodes as its
a bit simpler.
If you don't have hardware lying around, you can use
virtual machines, such as qemu, xen, uml, or VMware.

Yes. Assuming you want load-balancing, you need to use
lvs-dr for such a setup.

But again, I recommend starting with something a bit simpler.

Note, there is also lots of other documentation around, such
as the HOWTO. I just use those links as I wrote them and
thus am quite partial to them.
