Both the 50mm f1.8 and the 35mm f1.8 DX will work on the D90 with no problem. I use both on my D300 but I prefer the 35mm :

- I find that the "normal" view of the 35mm is more useful than the "mild tele" view that you get with the 50mm. But this depends entirely on what you use it for. If you want it for informal portraits under low light then the 50mm is nice
- The 35mm is full AF-S which means that you can adjust the focus manually just by touching the focus ring rather than having to mechanically uncouple the autofocus (on the 50mm f1.8)
- As the 35mm is AF-S it also works on my motorless D60 (but that doesn't concern you)

When you get your 18-105 (or whatever), leave the zoom at 35mm and then at 50mm for a while and see which is more useful.

BTW: The 18-105 VR is a nice lens by all accounts - but it's still mostly plastic. If you want something more noble with a metal lens mount then there's the 18-70, 18-200VR, 16-85VR or the 18-55 2.8
