Four tons is about right.
Starting the first of this year all AC units must have a minimum SEER of 13. There are a couple of more expensive options above this level but they probably aren't worth the investment. Your local AC contractor should be able to tell you cost of each and how much you will save with each.
Because many of the new units are not fully tested they may have some bugs, I would suggest getting a 10 year parts and labor warranty. Most better AC companies will offer this at a very reasonable price.
We just replaced our system with a new Trane and we got the 10 warranty.

In the range of 3.5 to 5 tons. There are too many variables to give a better answer. How much glass? What's your southern & western exposure. How many skylights? Cathedral ceilings? Window coverings? How many occupants? Insulated glass? 2-story? Older home? Well insulated? Do you have a kiln or other hobby-related equipment that emits lots of heat? Heat gain must be computed to refine an answer. You should be OK with a l3 s.e.e.r., but if you can bargain for more, at the same price, go for it. Good luck.

If your ceiling is normal height it should take a 4 ton air conditioner. My house is the same square footage and that's what mine has. The SEER rating is the effeciency of the model and should be as high as you can afford.
Good luck.
