I've got an old really beat up and pitted plane iron that I've been working
on. There's a lot of good metal left in the iron, so I think it's worth
cleaning up. After spending an hour attempting to flatten it with the P120
paper included with a Work Sharp 3000, I finally got it to the point where
it could be sharpened.
Would it be beneficial to go with a really heavy grit for the Work Sharp
3000, such as 50 or even 36? Do I risk leaving such deep gouges in the
metal that they won't come out with the next higher grit?

What's really taking the time is flattening the back. If I can get the
back flattened, doing the rest won't be difficult at all. It does cut
pretty nicely in the area that did flatten out, it's just taking forever.
Hopefully this will be the last time the iron ever needs such work.

I'm working on the iron (blade) and not too concerned about the plane
sole. This is a wooden plane, so a couple light passes with the jointer
should get everything square and flat.
Not skipping grits makes sense to me. I'm just looking at finding a more
aggressive starting point to try to make the job take a reasonable amount
of time.

Well, I picked up some 80 grit and gave that a try. It helped a bit, but
it will take quite a bit to get that iron to 100%. There's about 1/8-
1/4" on either side that isn't flat, but the middle is good. I'll just
have to use the plane like it's a smaller plane.

Boulder paper, eh? Scary stuff, Pucky.
That's one of the reasons I prefer coarse diamond hones. They'll take
down metal quicker if you need it removed. Grab a set of DMT diamond
paddles http://goo.gl/rdGf0 or an HF set of diamond plates.

individuals.
Alternatively, you can spend the extra time (and same expense) with
next higher grit papers. Whenever you use coarse grits, it's only a
matter of time to sand out the deeper gouges (when you have the metal
left in the iron.)

The gouging depends on how well the abrasive is graded for particle size.
I like 100 grit carbide powder (from Lee Valley) on a sheet of glass with a
few drops of oil for troublesome plane soles. This is a manual process, of
course, and if you're trying to do it exclusively by machine it might not
suit you. I can understand why, having invested in the Work Sharp, you'd
like for it to serve all your grinding needs.
The powder from Lee Valley is well-graded as to particle size, so you
wouldn't be putting in scratches that would cause you more than the usual
amount of work with the next finer grit.
But anyway, whatever you use, you then need to work your way through the
grits without skipping any until you get down to where you want to be in
terms of finish.

Sorry - I misread your post and thought you were working down an iron plane
sole.

Use the "heavier" grits to remove unwanted problem areas. the heavier
the grit the faster the removal of those particular spots.
BUT heavier grits create their own problems area and will need to be
remove step by step. The lighter the grit the more quickly/fewer grits
you go through before you can go to polishing the surface.

You only flatten the back once. ;~)

Yeah, pitting really hoses the edge, doesn't it? this is one of the
very few areas that a machine makes quick work of a sharpening task.
