Just bought some of the above on a whim. I think they may be a little much for my bike. Anyone have any experiences or thoughts on them?

Typical Marzocchi IMO, over heavy, not the most plush & I wish all the very best of luck getting them repaired if you ever have problems with them!
BUT IF you get a good pair-as rare as that seems to be, they seems a nice fork

I've had some for the last 10 months, and no problems as such. The damping is poor for high spped rocky trails, but that can be cured by an upgrade that is detailed on a long thread over on mtbr suspension forums HERE
