How many miles (km) are on your C5? If its not crazy high I would keep the stock oil pump. They are pretty robust and last.
If you are removing the heads to do the lifters then you would need to add head gaskets to your list, and head bolts since they are not re-usable.
Before blindly ordering pushrods, you should measure what the new combination will require. Chances are 7.4" will work, but its risky not measuring.

Couple things.
New valve springs will be needed.
With the duration of that cam it's going to be pretty lumpy compared to your stock LS6 cam. Will you have enough vacuum for power brakes?
Also plan for a custom tune.

To be honest, I don't think I would bother changing the lifters. If you do make sure you get them from a reputable place like BTR or Summit, and make absolutely sure that you only use OEM GM lifter trays from a reputable place too.

I agree with other guys here, but I do have 1 question. Who recommended 42lb injectors?? 42s are stock in the LS7. My built LS7 is using the stock 42lb LS7 injectors. Unless youre planning on doing a considerable amount of mods in the future, 36lbs would be fine, IMHO. 36s might also have a better spray pattern for your application than 42s. Just a thought......
I second or 3rd the posts about avoiding the Comp trunnion "upgrade." I had one, sadly. Then after I posted comments about the quality (or lack thereof) of the kit, some had the audacity to say I needed to do a better job of pressing on the bearing cups/races! Let me tell you, I have 44 years experience in this kind of work as a journeyman T & D maker. To be blunt, if Comp hasn't updated the steel used in the trunnion, and/or the steel used in the needle bearings, this kit sucks. I went with a Brian Tooley Racing V2 trunnion kit. Far superior to the Comp kit. If the OP goes with the BTR kit, DO NOT go with the V1 kit. Problems with the V1 kit. V2 is the superior setup......
