FIRST!!! Compression/leakdown test is what you should do before investigating any other issues. You may have just gotten used to the way the car feels.

Yes that would be a good place to start to know how well the engine is functioning. How many miles are on the car?

This is what I recommend on a new to you car..

Compression and leak down tests.
New Spark plugs cuz you pulled em out anyway
Pressure test the cooling system

If the engine passes the tests:
Change engine oil/filter
Air filter
Fuel filter
(already changed plugs)
change diff fluid
change trans fluid
check brake fluid/clutch fluid
visually inspect brakes, pull wheels off and inspect inside/outside pads
get an alignment
