Bill, before you do a coolant flush - check your delta again. The only reason I'm saying this, is because once you do a flush, you run the risk of clogging the oil cooler. And the risk is high. Be prepared to do a headgasket job almost immediately afterwards.
If you do the flush, and your deltas skyrocket (which they might) then you've successfully clogged your oil cooler. In that case, DO NOT continue to drive it. You can cause a lot of damage to the heads should you continue driving around with a clogged oil cooler. A clogged OC causes the EGR valve to fail (which you're already seeing), which will then leak coolant into the cylinder heads, then there's the combustion (or lack of) that causes pressure to lift the heads, stretching the bolts, and blowing the gaskets. Continued driving in this situation can cause irreversible damage to the heads (cracked heads, replacement).
What I would do for right now, is get an EGR delete kit (you can find them for around $150) and an SCT Programmer (or whatever of your choosing) to remove the check engine light. Hang tight until you get the funds squared away for the job that may, or may not, be at hand. Until your deltas get in the "danger zone" I wouldn't sweat anything right now.
This, of course, is just my opinion. Do your research - and if you have any questions... feel free to ask.
