Exactly my progression, though I haven't picked up my Minolta X700 in four years. I think my days of film are done.

This. Walk through it with manual in hand (or even better with Mastering the D300s by Darrell Young or some similar guide). And again. Don't try to do too much at once. Shoot a few hundred frames. Review. Try different options and settings. If you're proficient with the D70, you won't have difficulty getting up to speed with the D300s, but it may take awhile to fine tune it to your preference. There is a lot that you can customize, if you so choose.
Lenses are secondary. Whatever works on your D70 (for me it was the 18-70 kit lens and 70-300ED) will work fine on your D300s. If you need (want?) better lenses, that's a completely different question from the camera body.
