I'm suggesting the 12-24 for Bryce and other views--also the 50 f/1.4 for low light and the 24-120VR for walkaround-- Would the 28-200 be a better choice for walkaround because of size.. The VR is a big advantage in the 24-120...

Good advice you're giving your friend.
If she's predominately shooting landscapes, this is a great mix. I use the 12-24mm extensively now, and my 18-35mm is pretty much sitting to the side. OTOH, if she can't hit the cash for the 12-24mm, the kit lens will do a credible job combined with the 24-120mm for most things.
Opinions are mixed on the 24-120mm, but Thom Hogan's given (as usual) a balanced assessment at
http://www.bythom.com/24120ens.htm . I personally find that Thom's comments match my experience pretty well on this lens.
And, FWIW, the 24-120mm AFS/VR has a good "price point" for your friend, especially if she's going to get the 12-24mm AFS which is not a cheap lens.
If she goes with the kit lens, she may want more reach at lower cost, and the 70-300mm would be an inexpensive way of getting more reach. My (very) limited use of the lens suggests that it's pretty good stopped down at the mid- and longer end. Again, Thom Hogan's review may be of some use -
http://www.bythom.com/70300lens.htm . Note that Thom tested at f/22 with not great results - I didn't do anywhere near as much in my two day use of the lens.
The 70-300mm lens is also darned light in weight, an item that you noted as important to your friend. By comparison, the 70-200mm AFS/VR is a
lot heavier, as is the 80-200mm .
Also important to consider is that people like you and me who have lenses like the 200-400mm AFS/VR sometimes get a bit spoiled with what we shoot with (well, just me maybe - I think you're a nicer person

). It gets easy to look down on lenses like the 24-120mm or the 70-300mm when we have such great glass. Your friend, if she's starting without high end glass, may well be able to get fantastic images with those lenses, and not feel at all "deprived" in her photography.
IMO, at least.

P.S. The comment from MontyDog on getting her up the learning curve for the D70 is also darned good advice. If she's comfortable with the basic functions of the camera, the process will go nicely. If she's not at least versed in a few of these things on the D70, it won't matter if she assembles a $10k lens kit for her shooting pleasure.
