In my opinion keep the rock alive in saltwater and preserve as much life as you can. Do not use bleach or acid for live rock. Save the benefits. Normal reef temperature for you with a heater and some flow. I would water change often. I would take a power head and blow out the rock too. Get it right in the holes and watch the detritus flow out. Best to do this before a decent water change.
Any issues of algae to address on the rock can be done during curing. As your rock is live, it should cycle quickly when it is fully cured.
EDIT: it is essentially cycled, it just needs to process any die off.
