I would like to create a vlan for rspan type traffic is there anything special I need to declare in the vlan?
All the information I have seen also just talks about switches will I be able to go through a router with the traffic to my destination switch and port?
I also seen in some books that the vtp type is set to transparent is this needed?
Any good links to any information would be greatly appreciated.

You don't say which device you are looking to configure it on.
RSPAN will not work across a routed network so all your switches need to be interconnected via L2 trunks. If you need to SPAN across a L3 network some switches like the 6500 support ERSPAN.
Attached is a link to configuring SPAN/RSPAN/ERSPAN on 6500 and in the restrictions it does not say you have to be in VTP transparent mode.
If you are using other device let me know.

Here is a link to the 4006 configuration guides -
but as already said RSPAN will only work across L2 links.

This is what you need to do for rspan vlan.
SW1(config)#vlan 100
SW1(config-vlan)#remote-span
SW1(config-vlan)#end
But the rspan vlan traffic has to be in the interconnected switches and not through any Router in between.
