Can I do better than the 24-105 kit lens?

I am new to digital photography...making the jump from film and point and shoot cameras.

I just ordered a 6d kit with the 24-105 lens.  It will be here tomorrow or Tuesday.  I'm not sure if I should keep the kit lens or sell it and go for a different mix of lenses.

I almost always shoot scenery and architecture (rustic buildings, farm equipment, etc.) and night sky shots.  Not really into sports or wildlife shooting.

I really enjoy ultra wide lens shooting, and I am not sure if the kit lens will satisfy me...I'm on a tight budget right now, so I can't just go and buy a bunch of lenses.  Should I sell the kit lens and get an ultra wide and a cheaper zoom? Any advice would be appreciated
