Yes, I think you can get by with either of those two routers for your first.
You'll want to make one of the Karol/Wells precision bases for cutting rosettes and sound hole and you can also add a piece of 1/2" plywood to the bottom of the measureing arm to make an edge guide for cutting your truss rod channel. Or you can just mount the router to a piece of plywood, clamp a solid straight edge to the plywood and you have a router table with a fence to cut the truss rod channel.
Then you'll want to make some sort of fixture for cutting binding channels. You don't need to get to elaborate with it, check the archives for some good ideas,
here's a binding jig from Alain Desforges that would be pretty easy to make, or you can try
this one which will also work well.
Oh and the dremel you can make a base for as well for doing inlay work. Check out
Mario Proulx dremel base for a simple solution.
