Sizing for heat pump

I will soon be replacing this 2 ton package unit but I noticed it's a 2 ton.
I have a 1 level 770 sq ft area though.[2ton is oversized, on chart for middle tn]

Should I go with the 1 an a half ton vs 2 ton?

Also I noticed blower motor on old one shaking quite a bit as it's running,is this normal?

Only true way to know is to do a heat load on your home. Your HVAC contractor should be doing this without asking. If they don't find another one.

I was looking to replace it myself.

I'm thinking I'll stay with what size it has, seems that size works well an evenly distributes air.
Though it's not correct by the chart .

Much more is taken into account than the square footage. If the 2 ton is working fine, then I'd stick with 2 ton. If you're referring to the blower wheel inside the air handler, the squirrel cage could be out of balance. Or the motor shaft could be worn. May be repairable.
