i wouldn't rejet it at all, i've noticed these engines tend to run a little rich anyway. you're not going to have pinging issues on a 22R with a carb, especially with an early engine with only 9.0:1 compression!
all you need to do to kill the EGR system is get block-off plates and install them in place of the EGR valve on the head and the pipe on the intake. you can get rid of a lot of vacuum hoses this way as well, this is how i have my truck rigged up(carb is off being rebuilt right now), it runs GREAT like this.
i've only got the advance/retard on the distributor, AAP, choke opener, and choke breaker hooked up on my truck. i don't have a thermo switch(aftermarket air cleaner) and no charcoal canister so i blocked that port off:
