2002 Toyota Camry

Shakes or Wobbles problem
2002 Toyota Camry Automatic 90,000 miles

Hi everyone, I recently got a 2002 camry with 90,000 as a present and have been driving the car less than 2 months. The first thing I noticed was that the car had terrible handling, it always felt like I was driving on a flat tire, shook and wobbled at everything. I went ahead and changed the driver's side front tire and now the car drives extremely rough and my steering wheel is very heavy. Just yesterday I noticed it seemed like I was losing pressure and had very little acceleration with a lot more effort. There also seems to be a loud humming sound. I'm getting suggestions from wheel balancing to changing spark plugs and air filters. Please can someone tell me where to start? I dont know a lot about cars. Thanks guys!
