I also just came from a D90 to a D300s, and I have to say I'm loving the D300s!
While the menus are deeper, the controls are much easier (switching metering modes, AF modes, etc.) since many of them are now a hardware switch.
All the things that cause hesitation and delay are now gone (at least the ones caused by the camera and I am really comfortable with the D300s. I don't miss the D90 at all (and I loved it).
Despite the fact that I really dislike Ken Rockwell (he's the Rush Limbaugh of the photography world - an arrogant, condescending, self-contradicting gas-bag that will say anything to generate clicks and money), I did find his walk-through of the menus generally helpful. His comments on going to full-frame are a great example - aside from the significant additional cost to us peons, it puts you in the world of more-expensive FX glass not to mention that many of us chose DX specifically for the crop-factor field-of-view, which is a benefit to sports and bird/wildlife shooters (also ignoring the 40% faster FPS rating, video, dual slots, smaller size/weight if you care about those things). But I digress...
I also read through the manual. David Bush's guide has good reviews on Amazon.
Lastly, I like Lexar Professional cards. They have been excellent and I trust their quality. I have Lexar 400X SDHC cards from my D90 days and my 1000X CompactFlash are on the way shortly...
