Internet in Garage - Powerline Issues

Done correctly, no.

You should get full gigabit speed (assuming related equipment has that capacity) as long as total length is no more than about 100m, and there are only a couple of connections (with related changes in cable impedance) along the way.

Great thanks.

I'm assuming it wouldn't make a difference if one end of the cable is connected to a modular plug (connected direct to router) and the other end to a faceplate? Or would they need to be the same?

You can have one end a modular plug and the other end connected to a faceplate.
If connecting to a faceplate make sure the twisted pairs are twisted as close to the connections as possible.
