Engine flooded: Help fast!!

Got it Fixed this morning! I went out at about 11 and the thing was still stuck, didn't even crank all the way over. So, I disconnected all of the injectors and coil packs and removed the spark plug from that cylinder that the gas leaked into (also the one with the cracked o-ring). I heard pressure release as I took it out. I took a thin wood stick ad put it in to see if there was anything in it, kinda like a dipstick. I pulled it out and sure enough there was about 1/4 inch of WATER on it. Didn't smell like gas. It was water. I had been raining here for a few days. I guess it got on my intake through my open hood scoop and got by that damn o-ring. I cranked the engine and about a cup of water comes shooting out about 20 feet. After about 2 turns, I squirt a little ATF in the Cylinde, cranked a few more times and put the spark plug back in. I turned over and ran like a champ. I had a little too big of o-rings on the noszles, so I replaced them all with the right ones. Now my idle is rock solid at 800 instead of 1500 like it was. When I disconnect the IAC the car dies like it should, it also feels like I gained about 20 hp. I also found a coil pack with a torn wire on it. I was only running on like 7.5 cylinders. I fixed it and now it runs so smooth. Before it idled like a '69 camaro with a cam. Now it is baby smooth and alot quieter. Exhaust is alot smoother now too.

Oh yeah, should I put new spark plugs in. The one was completely soaked. I hate to put new ones in now because I am going home in 2 weeks and I have a set of autolite 764's already side-gapped and gapped. Can I go 2 weeks like this. It seems to run better than ever.
I am thinking I sjhould change oil now too. Should I? It only has 300 miles on a full mobil 1 change. I hate to have to throw away $50 if I really don't need to.
