Compression Test completed

Ok well, lots of mishaps while doing this....first, we forgot to take out the fuse and crank the engine before removing the spark plugs...so basically, there was a **** load of fuel in the cylinders unburned....hooked everything back up, drove around, and then did the test....I dropped one of the coil pack screws into the engine bay from hell somewhere....The front cylinders were exposed, but im confident (i sure as hell hope so) that they didnt fall into there....Then we started up the test, front 3 cylinders were from 180-190, but then we realized the coil packs and spark plugs were still in the back...we took them out, and then finished up the test...The results are as follows...(while looking toward the engine bay from the front)

Rear Left : 201 PSI
Rear Middle: 206 PSI
Rear Right : 211 PSI

Front Left : 200 PSI
Front Middle : 200 PSI
Front Right : 209 PSI

we cranked the car about 8-10 times each time, and stopped cranking when the gauge topped off....

I just have a few questions...

A) Is this ok? I know standard is 185 PSI, but I do have ~65k miles now.

B) What can I do to lower it back to the norm?

C) Will that little screw cause any kinda problems?

D) When I was cranking the car with the spark plugs out and the fuel pump fuse still in, I got a front heated O2 sensor code...im assuming thats from all the fuel, and it just needs to burn off? It wasn't there before...

thats it...thanx for all replys

you are only suposed to crank the engine over 4 times for the most accurate readings
