As others have said, just let it sit for another two weeks or so.
The gravity is *probably* where it will finish out at, but letting it sit will do nothing but help the flavor of the beer. Kit instructions generally try to rush you through the process (the less time an impatient new brewer needs to wait, the more likely they'll be to buy another kit
). Read up on the forums about fermentation and you'll get a good idea of what to expect.
As a good rule of thumb for most beers...give it a month in the primary fermenter. As long as the gravity readings remain the same for about 3 days in a row towards the end of that time, go ahead and bottle. As a new brewer it's hard to wait this long for a beer to finish, but the off-flavors produced by the yeast will be cleaned up the best by allowing this extra time.
Be patient, and welcome to the hobby
