Need help wiring 3 zone valves, a relay switch, & taco pump

Hi all Iím setting up a three zone valve system with 1 Taco pump for radiant heat. Iím almost done with the soldering and pretty soon I can start with the electrical. I have the following material and was hoping someone would be able to help me wire the entire system or send me a diagram. So here is what I have:

3 - Honeywell V8043F1036 Zone Valves
1 - Honeywell Hydronic Switching Relay RaA89A1074
1 - 40 VA transformer
1 - Taco pump 007
3 Ė tsats (2 heat only, 1 heat/ac)

For what are you using the switching relay? Normally with zone valves, you don't use a switching relay.
Is there a second circulator other than the one on the boiler? What is the number of the aquastat on the boiler?
Some photos might help. You can post them on photobucket or similar site & provide a link here.

Or get a Taco ZVC-403 and the wiring will be oh so simple.
