Heath,
I haven't yet decided on a rear table design, but I'm definitely planning to make one. Right now I making do with roller stands when the boards are long. I hate doing it this way and it's a good incentive to get me going and build something soon.
Peachtree has a cast iron router table extension (I think intended for the left side of the saw) that you might want to look into if you are going to attach your router table to your saw. I had my router table attached to my last table saw and wasn't all that happy with it, so I'm building a separate router table this time. There's nothing specifically wrong with having your saw and router table together. It's just a personal preference on my part. The top and fence of my new router table will be from Mark Sommerfeld and the whole top will hinge up instead of having a removable insert, as I've had router table insert problems in the past. I like the size and design of Mark's tops and fences because they're very solid and his fences move and adjust very easily, but also become very solid when locked in position and they have T slots for featherboards in both the table and the fence as well as replaceable zero clearance inserts in the fences.
