DB2 rebuild - what else to check / replace?

So my high-mileage DB2 needs to be rebuilt. It's leaking fuel from the throttle shaft and I can't do the repair myself on the truck without removing the intake manifold which is more work than I want to take on right now.

I want to get your opinion on what else I should have the shop look at while they're tearing off the intake / fuel pump - what else should be checked and changed?

Here is my current list of possibles:

1) Passenger side valve cover is leaking, replace / re-seal
2) HP fuel lines are rather rusted... Consider replacement?
3) Fuel injectors likely have a lot of miles on them - pop test? Replace?
4) Glow plugs working fine, but good idea to just replace?

What are your thoughts on the above list and what else would you have looked at / done?

This is a 6.5L non-turbo motor with ~200K miles on it.

Your suggestions and comments are greatly appreciated - thanks

If you do the valve cover issue you might as well do both and while you are in there replace the Nylon Rocker retainers..

Go through your entire fuel system from Tank Sock to IP.
