I think, if you bought the written materials for anybody's dry suit class, there'd be some well-organized information there.
Dry suits aren't rocket science, and you are not a new diver. The big things about diving a dry suit are avoiding feet-first ascents, and developing a rapid and sensitive awareness of the need to adjust buoyancy, because you simply can't do it as fast, or from as many positions in a dry suit as you can when diving wet. Some of that can't be taught, but simply has to be learned; even if you took a class, it would be wise to keep your first dozen or so dry suit dives relatively shallow, in case you lose control. Classes teach recovery procedures, but I have to say that, in my unfortunately not insignificant experience with feet-first ascents, you simply don't have time to execute them in most cases. Avoidance is a far better strategy!
In addition, there are things to learn about dry suit care and handling, most of which I think you can find in SB threads -- rinsing, seal care, zipper care and appropriate products have all been discussed here.
I don't think learning to use a dry suit is beyond the scope of someone who is experienced diving wet, and has good buoyancy control. An instructor might be able to shorten the process, but you can do it yourself.
