you wont go wrong with MSD's , I hear alot of people here like them and the Taylor wires.
and yes you just pull em off and stick the new ones on. ( just make sure you keep track of where they go! )
have fun dropping your 60 bucks and I hope it goes smoothly.

 

Lordco's got them, I think they are on sale right now. It's easy, just keep track of which wires go to the which cylinder.
