You're welcome.
As far as the router, Linksys is certainly a reasonable choice maker-wise.
And short of having Comcast come and make the switch (for a service call fee, of course), your approach is a strategy. Do you know much about how things currently run, cable-wise? For the best performance, fewer splitters (with appropriate signal capabilities) is important.
Another thing to consider is how your home phones are wired. Just because you have access to a phone jack in the new location doesn't mean it will allow you to have every phone in the house covered by the eMTA. Chances are the original install tech chose the current location because it provided access to the proper phone wiring node to do that.
