Hello,
My replies are in line. But you should include an ASCII topology to give us
a better understanding of what you are trying to accomplish.

How many routers will you have? one, two. With this two subnets in one
router means you'll put them in two different interfaces. If you are going
to put this in one ethernet interface, you'll not be able to trunk using
ethernet interface.

Yes, you can but the better thing to do is to make the vlan interface be the
default gateway for your PCs.
For example:
Cat5509 ----ISL----Cat6509 w/MSFC
| | | |
| | | |
PC PC PC PC
(V1) (V2) (V2) (V1)
You'll have two vlan interfaces at the MSFC and the PC's in V1 will have
their gateway point to vlan 1 interface of the MSFC and the PC's in V2 will
have their gateway point to vlan 2 interface.

Yes, it will point to the next hop router if that router have all the routes
to anything that the MSFC does not know about.
ip route 0.0.0.0 0.0.0.0

Yes, both the switches can be in server mode but they have to be in the same
vtp domain.
>Do the trunk ports have to have an IP address ?
Trunked ports betweeen the 5509 and 6509 are layer2 ports they do not have
ip addresses.

You don't put a subnet in four diffrent vlans that' not the purpose of
vlans.
VLANs allow you to group ports on a switch to limit unicast, multicast, and
broadcast traffic flooding. Flooded traffic originating from a particular
VLAN is only flooded out other ports belonging to that VLAN.
