B&W scanning and developing help?

[another view]

This shot was taken last summer on Tmax 400, and developed in Tmax developer per their recommendations. It's pretty grainy for 400 - I haven't tried to print it either digitally or in a darkroom, but this is how my negs seem to turn out. Where am I going wrong? I haven't done any darkroom printing yet, just developing.

I haven't worked much with scanning negs lately (slides, not negs) because I always had bad luck with color negs. I used to shoot alot of Royal Gold 400 and got pretty good large prints but couldn't scan it for anything due to grain and color casts. I did try to scan some T400CN (C41 process B&W) the other day and the results were great.

My scanner is an Acer 2720S which is probably not the greatest but can't be the biggest problem here. First one is right out of the scanner (adjusted levels though) and the second one is after trying to reduce grain in Photoshop. Any suggestions?
