Well, we're using 100Mbps and Gigabit Ethernet as the "WAN" connection.
(actually MAN connection). So we're going to have one port on the 3550
that's a routed port and the others are simply switched. We'd like to
get rid of the other WAN connection (i.e the frame relay or PTP T1(s)
we're currently using). So we could keep the "old" router there (and
let it do IPX only) as the tunnel endpoint, then tunnel the IPX back
through the 3550 using IP over the "MAN" connection back to the 6500s
and terminate the tunnel there (where the 100Mbps/Gig MAN connects to).

The 3550 doesn't have any WAN interfaces, so you must have a normal
router there, right? Put that router's ethernet interface in a VLAN
along with the IPX clients. Route IPX normally over the WAN, and let
the 3550 and the router route IP between VLANs and to/from the WAN.
This assumes both edge devices can route IPX, which they'd have to if
you were going to tunnel it. Of course, if there's a bunch of routers
involved, routing IPX might be tough.
