if you're just setting up your tank you don't need to cycle your rocks separately.
If you bought dry base-rock from the LFS
, I would simply rinse it well with just plain water and arrange it in your tank as you'd like. Get your tank up to temp and SG
and drop in your shrimp to kick off your cycle. If you plan on adding LR
do it at this point and you can possibly skip the shrimp and just let the LR
kick off the cycle if you're adding enough.
In regards to lighting; IMO
an algae bloom after an initial tank setup is just part of the setup. You can minimize the bloom by using a reduced light schedule and by doing a hefty water change at the end of the cycle, but I wouldn't take any drastic measures just to try and avoid algae when setting up a new tank.
A lawnmower blenny will help with algae, but don't get one to correct you're algae. If, after your cycle and settle of the system you still have a lot of algae look to your maintenance habits and feeding habits. A balanced system with decent maintenance habits and a minimum cleanup crew should have little nuisance algaes.
