Engineer Goby and Rock Stabilization

I have a 180G tank which I moved into from a 75G. I lucked into the best deal today on Craig's List; I bought 100 pounds of LR covered in corals and a 12" Engineer Goby. I go to pick up the Goby tomorrow and I am wondering how I can stabilize my rock better. I have some really large rocks in there, I think a couple of them are over 20 lbs and they are sitting on the tank bottom. I am not so much worried about the large ones, it is the smaller ones stacked on top of the larger ones.
Can someone point me in the right direction?
Thanks!
