The hardware depends on how many active classes you will have and how
complicated your filter rules are. I once create a few 1000 active classes
on a 486 shaping 10Mbit and the box survived it. The filter rules where very
simple.

You can use kernel 2.4.20 and configure it as bridge. If you want to control
the traffic, you also need ebtables (this is iptables for a brdige).

Yes (I think).

Or install it on a fast pc and switch the disks. Works great :)
