Right now I'm more interested in just getting started, so whatever would have a smaller learning curve in the beginning. I have had experience with installing c

  The key question to me is 'how embedded'? On smaller embedded microcontrollers there is a 'main' with "for(;;)", and you have to manually schedule various tasks. Arduino makes it very easy to get started with this level of embedded. However, if you're after incremental steps on top of dd-wrt, set up a cross-compile toolchain for arm and start by just rebuilding the dd-wrt firmware you've already flashed. After you get that, make a "hello world" for the home router that blinks a light and outputs via serial. It'll give you a good feel for certain aspects of embedded development. Have you tried to add USB to a home router? Certain models of router make this a relatively doable task, and there is usually at least a minimal bit of help (over doing it from scratch yourself), but you may already have most of the hardware to do it, possibly making it easier to start on.
