1) If you still have air in the injector line... With the engine running, loosen the injector hard line at the injector (just slightly), it should get most of the air out and then start spraying diesel. I believe it takes a 14mm wrench, or a crow's foot (dealer).
2) The delivery valve seals are pretty easy. You just have to make sure that the IP is clean, and nothing falls into the delivery valves while you're taking things out. You'll need a special socket (splined) from the dealer. It takes 5 o-rings for the OM602, about $1 each from the dealer. There are also 5 copper washers, although it's debated whether or not to replace these. Here's the DIY article:

One you do those, you'll need to get the air out of the lines again. It takes a bit of cranking, but, with a solid battery, it's pretty easy.
