Your plan looks good, Just one thought for you to consider.
What are you planning your efficiency at to hit your OG? My first couple of AG batches had terrible efficiency (60-65%) and I badly missed by target OG. I changed a couple of things, but by far the biggest thing that increased my efficiency was increasing my water to grain ratio. I started at 1.25 quarts/pound I increased it closer to 1.75-2 qts/pound and that made a big difference. I've never had an issue with my ph getting out of hand, but if you have some ph stabilizer, it wouldn't hurt to use it.
Like I said, your plan looks good, but if you miss your target OG, try adjusting your water to grain ratio next time.
