As far a rockers go, I personally would not go above 1.9 ratio. Any higher than that and ive seen a fair few people around that have run into issues. Either mace or yella terra seem to do the job (id steer clear of FIT) and should take a mechanic no more than 1 hour labour to install. If you go second hand keep in mind that some rockers come with torque to yield bolts which means once the bolts have been used once they need to be thrown out and new bolts used. I think yella terra use reusable bolts but you should double check that.

The pulley wont make it whine much for normal driving, mainly just under load at higher revs.
