You're worried about lenses... Obviously you bought a body, so you need at least one to take pictures with... What I would be more concerned about is the fact that your last two shot, of landscapes, your horizons were noticeably not level....
Which can be fixed in Photoshop, so I have no idea what you're going on about. But you digress, so back to the topic on hand.
Totally agree with bvukich, would have gone with the kit, the 24-105 is a great all round lens, but in the absence of having one, I'd suggest at least a 17-40 f/4 L, which, if you're after landscapes, should be a nice lens to use, not much difference in this and the faster 16-35 when stopped down, which you'd be doing when taking landscapes (generally) anyway. Pretty cheap too, so its not gonna blow your budget.
Interestingly though, while you missed out on the 24-105 f/4, you've given yourself a chance to go for the 24-70 f/2.8, which is also a pretty good all rounder, but also cover your landscapes AND portraits if need be. A 50mm f/1.4 (The Sigma is another possibility (HERESY! I hear you shout... nevermind =P)), or the 85mm would be beautiful, or go for the longer 135mm. (which could help get shots of your "uncooperative" daughter - can't be uncooperative if she doesn't know she's in your sights.
70-200... I'd put that off first though, from what you describe I don't think you'd need to go into that range yet... but thats just me.
Thats just me though.
