Beginning bench set?

I'm completely new to weight lifting. So far my exercise routine has been very mild - a few mile uphill walk daily, some bicycling, beginner dvds. My overall goal is not to lose weight but to tone up. I'd prefer to gain weight, but as I've been very inactive the past 10 years many of my previously firm areas have turned, well, jiggly.

I'm honestly not sure where to begin, but I definitely want to incorporate weights and work out at home. My reading so far seems to point in the direction of at least a weight bench, but I'd like to get opinions to make sure I'm buying the right starting point.

I can currently do under 10 or so standard pushups with good form, not a single pull up, and have trouble with squats/lunges due to some knee pains. Would something like this be the proper starting point for me, or should I be looking for something else?

Ideally, my target zones are my butt and thighs, but I certainly wouldn't mind a little toning up everywhere else as well.
