Would I be right in saying the only real difference between the 2860 and 2760 is the two extra ethernet ports? I have noticed there seem to be far more people with the 2860 and that means we can also support each other on most issues.

i think here are more users owning business, that is why seems the 2860 is more popular
The 2860 as more expensive unit has a lot different than the 2760 which is also fine for home soho or very small business

as hardware only then yes
-2 extra ethernet ports
-the 2860 plus has an extra antenna in the middle for 5 G (dual band) the 2760 no dual band
-extra incoming wan port ... 2760 not has

but for software here some basic differences
-more vpn tunnels
-SSL VPN
- VPN tranking
-higher firewall throughput up to 200 mbps ... 2760 seems only about 90 mbps
-Load balance ... 2760 not has
- analoge dial up for 3G/4G usb modems - 2760 No

Plus some small other differences i am not remembering right now :o

But how about for basic "how to" questions like "how can I set up port forwarding" and the things you see on here? That must be fairly similar? A lot of it must be?

Most of them are about the same ... at the moment for port forwarding you mentioned with the 2760 needs to go at Network > NAT > Virtual Host, while the 2860 is at usal NAT >> Port Redirection
Other example bind IP to mac is at Network > LAN > Ethernet
Latest firmware has moved back to the original place few features and hopes will do this in future
For a demo Take a look here to understand better using it, if will help you ... note most of the settings needs to press the add button on top EDIT sorry left of the menus
