Can't figure out what is wrong...

Ok, I recently replace my Valve Gasket...upon start up car threw
11608 DME Digital Motor Electorincs, internal failure, cotrol nominal torque
But car ran ok. So I came back from test drive, Uploaded PROceed 11-25 map, Command center, reset all values. Test drove and no codes...sweet!

So next morning, I took my car to the track, on my way to the track, I did few 3rd gear pulls, car felt great!....SES light came on but my drove normal, no hiccup, no limp. As soon as I got to the track I hooked up my laptop to see codes.

12000, 10703, 11518, 11529, 11610(control motor torque limitation) But again car was running good. Spent 1/2 day at the track, still no sign of limp or any other problem except power steering fluid over flowed but told it's normal after hard tracking.

On my way home, I turned on my Performance Steering wheel and noiced 405 Water Temp/236 Oil Temp. Ok....WHAT!? 405????? Car was still boosting fine with no sign of limp or Engine overhear warning, but one thing I noticed was even though I was in "DS" mode it drove like I was driving in "D"
Stopped the car, turned it off, restart, everything went back to normal again. Water temp/oil temp normal. So I drove home fine. Next morning, I start the car, everything seem normal but as soon as I drove off the lot, I saw Water Temp increasing fast and again reached 405. Fan on full blasting...took my car back home scratching my head...wtf is going on!??
After searching through forum, here is what I gathered.

1. Could be blown fuse
2. Battery need to be disconnected for 10mins to reset since I unplugged bunch of stuff while replace valve gasket
3. Replace water pump/ thermostat
4. Reload Map/Firmware until everything is ok

P.S. Call me an idiot since I forgot to disconnect battery before performing valve gasket replacement....could this caused any problem I am having right now?

Any input, help would be greatly appreciated!!
