Juan Foote's post (#2) tells you almost all you need to know. What he didn't mention is that the bikes that he bought from Bikes Direct almost certainly cost at least two or three times (or more) what you're proposing to spend. I bought two bikes from Bikes Direct, and I'm still delighted with both, but I spent over $1,000 for each.
If you are determined to get a bike with suspension despite the warnings in the subsequent posts, you'll probably get reasonable service out of the bike if you stick to the uses that you described (paved surfaces and jogging trails). Ironically, entry-level suspension will hold up for pretty much any use except riding on trails where suspension is needed.
