What year is your truck? Need to know that in order to see what programmer is available for your truck.

I would leave the o2 sensors in as your A/F ratio varies with load and the computer needs to get readings from them to adjust fuel delivery given engine demands, load, ambient conditions, etc...

The rest of the exhaust system leaks should be repaired for sure.

Good luck!
