I would run cat5 to each light switch, which gives you up to 4 pairs alolowing you up to 4 buttons per wall switch. You can see them here
My wall switches (all must be momentary switches) were clipsal type origionaly but after my velbus install I managed to get some lovely brushed steel, screwless minigrid switches which really look the part, you can see them here

For the dimmer, I used a the vmbdmi module which is a 1 channel dimmer, so you would need 1 of these for each dimming circuit. You dont need any external dimmer to use with this unit. I have dimmable gu10 leds on them, and am happy enough, although perhaps a 12v led system might be better.
What you will need
Velbus modules
You will need a vmdmi for each dimmable circuit. These modules come with a PB (push button) input, which is wired to your momentary light switch via cat5.
If you dont want to dim all circuits, then you can use a vmb4ryno which will do 4 circuits for you.However, this unit does not contain PB inputs, so you will need to buy a PB module such as the VMB7in which gives you 7 pb inputs, and these can be configured to control any velbus channel.
When I did mine, I only had 1 dimming circuit, so I used VMB4RY modules which had 4 PB inputs already, so I didnt need to purchase additional PB modules. However, velbus dont supply this module any more.
You will also need a Power supply for velbus, and either a usb interface or rs232 for the initial configuration of velbus.
For Comfort you will need as a minimum
Main board
UCM/ETH03 (from connection to BB for smartphone app)
UCM/Velbus for connection to velbus
Keypads etc.
Depending on how many inputs you want on comfort, for example, connecting door sensors and PIR's you may need to expand the numer of inputs above the 8 standrad on the main board.
