Large for the MySQL is probably appropriate; I would do an nginx lb out front on a c1.medium. If you aren't doing ssl termination a m1.small may do fine. I think you've outgrown a t1.micro lb.
I've tried ELBs but I didn't like losing all control of the lb, and sometimes you need nginx's capability to solve issues, plug holes, throw up maintenance notices, and do other optimizations. Nginx is a veritable Swiss army knife to have at the front of your infrastructure. You can keep apache for your app server, I'd start with two c1.mediums for your app servers. If your platform is stable and a known quantity on apache switching is only likely to cause you pain. My guess is your sphinx servers would benefit more from ram than CPU so I'd probably run two m1.mediums there. Then monitor and adjust as necessary. c2.mediums are going to be your processing workhorses. In my benchmarking for app servers a c1.medium properly tuned is better than 3 m1.smalls. (and cheaper) If your serving php scalr's canned nginx, app, and MySQL roles will be fine for you. I didn't love rds; but If I inherited a project with it I wouldn't hate it enough to move it to non-rds instances immediately. Try running with it until it becomes a pain point; you'll have bigger fish to fry in the meantime.
