The top's going to get dinged up, glue, stains and other finishes
will get on it. SO - going with an easily replacable working
surface is something to keep in mind - 1/4" melamine or
masonite - screwed down - works pretty well. Flip it over
when one face gets too bad.. If you frame the top and use
a rabbet on top to hold the replacable working surface you're
less apt to chew up the edges of the melamline or masonite.
Round the otside edges and corners of the top "frame".
Sharp edges and corners hurt.

BTW - if you wax the working top semi-regularly, glue
and stuff won't stick to it.

Hang the cabinets/shelves off the wall rather than having
them sit on the bench top. Makes the top working surface
easier to replace. If you hang them with french cleats they
can be moved easier later if need be (you will re-arrange
things over time).

Go with adustable shelves rather than fixed shelves.

Wall space is always at a premium so consider doors
on the wall units and some of the peg board wall.
If the doors are 2-3" deep you can effectively almost
double your wall space storage capacity. If you go with
modular inserts you can re-arrange things as need be.
Doors also keep dust etc. off of the cabinet's contents.
Here's some stuff to consider
http://home.comcast.net/~charliebcz/...olCabinet.html

As for drawers, shallow drawers means more drawers AND
less digging down through layers to find what you want. Full
extension drawr glides also means less feeling around in
the back of the drawer. Also, holes in drawer faces let
things into the drawer you don't want in the drawer. Low
profile or partial insert drawer pulls would be preferable.

Mount the vise and the grinder on the ends of the bench top.
You want as much uninterupted bench top space as possible.
And if you're going to go with a metal vise, get one with
an anvil - that's handy.

Consider a power strip in or on/in the apron/stretchers or
the legs. Climbing under a bench to plug things in is a PITA
and power cords from the wall above the bench get in the
way.

You're going to probably need task lighting. Some holes in
the bench top for a moveable flex or goose neck lamp could
come in handy

Just some things to think about
