Default Brewing a Rye IPA, Mash water question

SO i'm brewing Northern Brewer's Denny's Wry Smile Rye IPA.

I have a 10 gallon round cooler system i'm using (fly sparging)

I'm using beersmith and the directions included, and the total grain bill is 16 lbs. Well, i used 8 gallons of water which comes out to about 2 gallons/lb. I preheated my mash tun, and my grain temps were at 77 when i added to the mash tun. I heated my mash water to 165 and added to my grains to try to get to the 153 recommended mash heat. Well, apparently i overshot, my temps were at 160. So i added 1/2 gallon of cold water to get it down to 153/154. It's mashing at the moment.

My questions are
1) Will too much mash water ruin my efficiency?
2) My 10 gallon cooler is pretty full with the 16 lbs of grains and the 8 gallons of water. When i start sparging, it doesn't seem like much will happen, because my tun is so full right now. Any help or easing of my tension would be appreciated.

This is my 2nd all-grain batch ever, so i'm still not 100% comfortable.

1. not likely
2. batch sparge (the way the recipe was designed! )

Well, i fly sparged the only other time i've done all-grain. As it sits right now, my 10 gallon water cooler has maybe 1 to 1.5 gallons of open space until it overflows. As i understand it batch sparging, is just adding a bulk amount of water at a time. Therfore, i have fears of it overflowing.

Also, recipe calls out for mashout @ 170 for 10 minutes. As i understand it, mashout is a sort of rest at 170. If i do the mashout, do i even need to sparge? Or is the mashout acting as a sparge?

No, the mashout is not acting like a sparge. I almost never do a mashout any longer, especially with higher mash ratios like you used. But that's batch sparging, not fly sparging. If you don't sparge, your efficiency may be low and your OG low also. Out of curiosity, how did you decide on 8 gal. of mash water?

Yeah, I realize that. I'm wondering why you didn't adjust it down a bit to compensate for the size of your cooler. Maybe that's just something I do. I use between 1.6 (most often) and 2 qt./lb. but I decide based on what the total mash volume will end up being.

Well, like i said, it's my second all-grain batch ever. So i didn't know that i could do that without having adverse consequences. I'll know better for next time.

You might want to at least look into batch sparging. I've used it to brew that recipe dozens of times and other recipes hundreds of times.
