Update:
Removing the injection pump input shaft seal with the washer method worked well.
Basically got a big 5/16" washer, 8 small screws (#4 1/2" long). Drilled the washer with 8 holes, and screwed the washer to the seal with the 8 screws, then could easily pry on the washer with 2 screwdrivers and the seal popped out.
Put in new seal, put back pulley and just got timing belt on before dark. Another note: Like Mark suggested in an email, my slightly off (3 degrees) valve timing was likely due to timing belt stretch. Indeed, when I tensioned the new timing belt everything lined up perfectly (valves, injection pump, TDC mark.)
Will double check tomorrow that I got it all right by hand cranking a few turns, the see if she starts...

Thanks Justin for pointing out a helpful tool. I did a google image search and found similar looking ones, such as this:

I'm still pursuing the "put some screws into the seal rim" path. Others use that strategy too:

If I fail I will have to look for the right size of your tool, try to make one (maybe threading an appropriately sized pipe) or I guess last option is to take the pump out and bring it to a Bosch injection service place and ask them to pull the seal. I would imagine they have the same tool as you showed in the images, but without personal contacts it is hard to borrow tools. (Justifiably -- when I was an apprentice in a machine shop the master would keep all his tools to himself, and we used a second set of "pre-abused" tools and machines)

We use this tool and it takes all of 5-mins, and can even be done without removing the IP on some rigs:
http://3.bp.blogspot.com/-sArUos2PqIk/ToMun_nciKI/AAAAAAAAA6s/KVGfYhclkKk/s1600/P1010593.JPG
The one on the L is for the 1.6 IP w/17mm shaft, and the one on the R is for the 1.9 NA/TD/TDI IPs w/19mm shaft.
I don't recall where we got these but they make this job a simple task rather than an onerous chore. You screw in the steeply tapered thread into the seal, get it nice and tight and then tighten down the bolt which creates counter pressure on the end of the shaft to press out the seal.
