Ive also been doing lots of soil testing on all our properties. My understanding is that you don't want to apply any more lime than 50 #s per 1000 sq ft. But if the recommendation calls for more you do the 50 #s wait a season and test again, and maybe apply again. The idea being that you will bring it up incrementally.
I feel soil testing is too often overlooked by landscapers. Besides the State soil testers like cooperative extension, there also a number of private labs out there that do it affordably and quickly (A BIG PLUS COMPARED TO THE STATE).
Also about working the lime in. I recently bought a Calcitic lime they say is a micro prill. Its basically super mini pelletized lime. That helps with ease of application, and is able to be watered in. Sounded like a winner to me.
One think I would like help with is I dont understand how the lime will affect the nutrient needs of the plants. For example if the soil test says you need 20 pounds of 10% Phosphorous per 1000 sq ft, wouldnt that need be changed when the acidity changes? Because at different Ph's plants are able to uptake nutrients or not. I would appreciate any comments on this.
