Reporting back... the job was harder than expected, but I think its mostly due to the shape of the floor pan of the van and a little tighter working quarters. Pins were hard to get out, harder to get back in.
Pins that came with my kit were too loose, so I wound up reusing the old ones. They only seem to hold the bushings in place and the shifter on one side, and the old ones seem to do that adequately. It helped a lot having a nice punch to get them in/out.
Original(?) bushings were all still present, but the bottom one was very worn and cracked thru in about 10 places. Lost one bit into the trans trying to carefully extract each peice with a needle nose pliers. Sounds like most wind up in the trans anyway, so probably not a big deal.
Drove it into work today and there was a noticeable improvement. Still grind a little into third every once in awhile but its not as noticeable. Biggest improvement was the downshifts... I can consistently downshift from 3 > 2, 2 > 1 whereas before it would take a few tries or I'd have to be at or near a complete stop. Overall, well worth the $15. Next step will be to remove the MC for a total bleed.
