Temperature Calculators?

I am doing my second AG this weekend with my buddy, and the first using our new 10 gallon MLT.

I am looking for some formulas or a webpage that has plugins so that I can figure out what temperature to get the mash water at, so that when I add it to x-lbs of grains it will be at y-temp...anyone have suggestions?

I am using the exact recipe that another friend did last weekend, he uses a multi step mash with tons of temperature adjustments and a bucket bag sparge, and I told him I can make just as good a beer if not better, and get better extraction with the new MLT and a single temperature mash.

I am assuming a mash at about 153*F for an hour or two with 4.5 gallons water, vorlauf until clear and sparge with another 2-3 gallons of 170*F water until it runs relatively clear and SG of runoff is about 1.010, boil down to 5.5 gallons.

Recipe:
1.5lb 6-row
1.5lb Crystal 75L
14 lb 2-row

4oz Cascade (50min)
2oz Centennial (50min)
4oz Fuggle (15 min)
2oz Fuggle (10min)

yeast: Strain isolated from Mt. Sun IPA

any more ideas/suggestions?

edit: Supposed to be a very hoppy IPA

Do a internet search for "Promash" or BeerSmith. You can download it for a trial period. It will also help with mash/sparge water temps and volumes.
I would recommend having 10-20% more sparge water than calculated ...its a pain to realize you need more..and have to wait for it to heat up.
Also, dont forget that the mash tun absorbs heat - so preheat it with boiling water or your mash temp may be low.

PS- 17 lbs of grain seems a bit high for 5 Gallons. (depending on efficientcy / method)

Cheers.

BTW: After posting this, I found a lot of this info in How To Brew...for those in the future who use the search function.

17lbs is a lot, it is a big IPA. 12oz of hops to match it...

ProMash and Beersmith are great, but you can also find a lot of the same functions for free, between sites like this, beer recipator, etc.
