Augment Question

First off, again, thank you to the group for providing such good info and advice. I started playing in 2001 and took several years off after Planes of Power, returning this year. I am now lvl 80 with 600 AAs and have a lot of gear from the special lower guk/blackburrow instances. My problem was an absence of augments, which I have not remedied thanks to this group. As an aside, with the advice from this group I was able to solo with a healing merch the aug camps in the lower zones and then, in turn, DSH (Dungore - with a group), MPG (Blind Hunter -- rare mob, but easy), RSS (both camps -- fun and challenging and I had some help along the way), Deadbone Reef (Gali -- very long camp), Valdehome (Royal Crypt Guard -- died here a few times and finally got lucky) and Dreadspire (Student -- again had some help along the way, and solo I died/ran for my life several times when I pulled three dogs -- chuckle). Next on my list is a return trip to Valdehome for the rare aug and a return visit to Ashengate for the Crest of the Scarlet Legion (I didn't get too far into the zone last time). I do not plan on even attempting to camp Alex for Stonewarden. Am I missing any a paladin of my level with a merch should have and can get solo?
Now that I have my aug spots filled with at least 20ac augs (except my charm), I have a few questions.
When do I start replacing my 20ac augs from RSS? Specifically, I have the new hotzone augs: 10ac/80hme and 10ac/45hm, should either or both replace my 20ac augs from RSS? I group when I can, but spend a lot of time soloing with a healing merch. According to eqplayers, my max HPs are 22,040 and ac is 3498 (although it is higher when I use a shield and when I use SoT).
Any advice would be appreciate and thank you again for what you have all built here.
Good hunting.
