Unfortunately, our support for the '905 currently *sucks*, so you're 
not going to be taking much advantage of them.  8(

They work, but you would be better off selecting a card that's better 
supported.  The Intel EtherExpress Pro 100+ is going for about $50 
these days, and these are the top recommendation.

This depends on your activity patterns.  If you have a single server 
and many clients, then a switch is less useful.  If you have a more 
incestuous arrangement, then a switch will give better results.

But unless you're really pushing the network, it's unlikely that the 
difference will be worth the cost.

We're using a Lantronix switch for the freebsd.org machines; it appears 
to work just fine.  I also have a D-Link 8-port 100MBps hub in my 
office - it was cheap and works "as desired".  YMMV.
