No they should already be on the radio.
Your got a link to the headunit, as some don't come with RCA, but this can be over come by using the speaker outputs using one of these....

You should have a pair of red and white RCA leads that are used to run the sound from the headunit to the amp.
You should have a set like this (below), running between the headunit and amp.

I had a set on my 172 mk1 and its the worst think I'd ever done never could get them set up right, either too hard or too soft.
IMO pay the extra and get H&R's, you maybe able to get a second hand set if your lucky.
Yes just plug in.
You may have to change the ignition wire and constant live round, so as not to keep reseting the headunit when you turn the ignition off.
