You didn't mention the extend of your experience, but it looks like you have less than 15 dives under your belt.
Given that, you may or may not want to go to the south side (deep side). That is the only side I've dove on. There is a cabin cruiser and a L.A.R.K. in close proximity in about 50' of water. I prefer this side because vis is usually 20-30' but it is cold (7mm needed).
However, you can stay on the other side of the quarry where it is shallower, and maybe can even stick with the 3mm suit. The surface temp is very nice, but below about 30' or so it gets chilly.
I suggest you buy their slate int he office. It has a map of the quarry with compass headings written in. I believe it's $4, so a great buy.
Also, I would take only 1 tank since they do fills there. They even have a pick up/drop off service for an extra $1.
Have fun!
