When you have ip phones, QoS should be addressed starting from layer 2. It is good thing let the swithes do QoS for your voice packets before they get to the routers. I think you can take a look at 2950.
As for the core, unless you will have some kind of MAN connections in the future, any reason you can not get by with something like 7200s? You have 3810 and no voice, I do not think you should repeat the pattern with 7600 and no gigabit. Any reason you want to replace FR with ATM in the future? Since you rely on IP QoS, what layer 2 you are using at WAN should not matter, ip/atm/frame/, as long as the carrier gives you the SLA you need for the voice traffic. If you do not have redundancy at your central WAN aggregation point, you may consider it right now, since voice is likely way critical than data for many compaines.
