hello,

  perhaps i've missed something, but it's not clear for me, how do dumb
PCs and workstations learn which router to send their packets to?

IMHO, HSRP is a waste of time in this application.

I'm in a similar situation, and am using OSPF to "load balance" and 
Provide "redundancy".

Always up on both connections, router table converges to take care of L3
connectivity, no wasted bandwidth on hellos.

Anybody see potential issues with this?

HSRP handles the Layer 3 failover just fine.  Use per-VLAN rapid spanning
tree to handle the Layer 2 cutover.  Set up the VLAN on an interlink port
between the boxes as well.  Set the spanning tree priority for your
primary switch to 0 and on your backup as 4096.

I'm doing this for our campus network using 6513s and 6506s in Hybrid
Mode and it works pretty good.
