I personally don't have issues with glycerin in my poos or rinse-out (just limit it in my stylers), so you're probably ok withe Deva NP & OC (just use a different leave in).
Since the humidity hit, I don't feel I really even NEED a LI, but when I do, I've been using Shescentit Okra reconstructor (has a lot of protein tho, so if you're truly coarse, it probably won't work for you), and recently CJ Beauticurls LI.
For cleansing conditioners, I'm obsessed with Curl Junkie Daily Fix. (Deva no poo is essentially a cleansing conditioner.)
For gels, all of them in my signature are glycerin-free (except the LA Looks mega gel, but it's really low on the ingredients list). I've been loving the cheap gels lately!
