I have my plant in a 10x10 pot and about 8" high and my plant is about 37" tall. Should it grow good in there? I have about 2 dozen tomatoes on it.

A 5 gallon container is optimal for a single cherry tomato plant. This would be about 12x12, slightly larger than you have, but your plant will probably do just fine, especially since it's already producing fruit. If it seems to lag at any point you could try adding a little extra compost to ensure it's happy..
