Questions about service

I am interested in taking advantage of deals you have running now and switching but I have a few questions:

1. I am considering switching to att for internet and tv...is 1GB available in my area and what is the upload speed?

2. Can I buy my own router and will there be a discount on my bill?

3. I had some issues with getting tivo working due to being on another subnet...will I have any issues with boxes like that? setting subnet on my TIVO to 255.255.0.0 worked for me.
