janglin is a bit out of my area of expertice, so i can't help ya there

on the Support side though, I'd suggest: Nami (decent heal that gets stronger for every bounce once you pass 200 AP), Janna (lots of CC for a squishy, plus an AoE heal and an AD boosting sheild), and Thresh (Thresh.)

Sona (HEALSHEALSHEALSAURASAURASAURAS), Braum (easy to trigger stun in bot lane, sheild is DEFINITELY a game changer), and Leona (STUNSTUNROOTSTUNSTUNROOTSTUNSTUNROOT) are also good, though they each have something missing from your reqs (Sona's amount of CC is relatively small, with only Alacrity Power Chord and Crescendo, Braum has no heals and instead takes all the shots for his teammate which can easily kill him against a poke comp, and Leona is also missing a heal and has to be a lot more balls out to do well)

As a side note, I personally have a little place in my heart for Support Karma, though she doesn't really fit your reqs much, ahaha
