I seem to spend a lot of the entire fight looking @ healthbars so can miss a lot of what's actually happening on Maexxna... but I noticed "target not in line of sight" problems for people who are webbed - although I thought that this was on the wall opposite the entrance.

Some other healers mentioned that they lost the ability to heal certain people on the wall about 2s after they were webbed. Is there any way at all of healing these people or is it just the case that the best I can do is chuck a renew their way the moment they're snatched?

I'm fairly sure that the bug here, is that you are able to heal them at all. My impression from the fight is that you are supposed to be forced to get them down ASAP or they die, with no option of healing them.

The healer thing on Razorgore I think might've bugged, tho it might have just been bad luck. I ended up kiting the entire room right up until the end of phase one. It was fun.

Yeah I agree with that. I mean, if you can heal webbed targets, this fight is BWL level... In fact, it already is. Just DPS down the web wraps, try to heal them, battle rez those you couldn't save @ 35% and collect loot. Way too easy for an end wing boss.
I'm pretty sure you could kill her without even taking care of webbed target. Everyone in full dps mode, you'll loose 3 guys / stun off course but.. who cares ? In 3 stuns you'll be at 30%-.

AQ40 wonkiness continues.

Wednesday: Skeram->Ouro, no issues. Friday: Can't teleport to the NPCs outside C'Thun's room. The only teleport option available is to the Twin Emps.

You cleared Skeram-->Ouro in one run and then stopped there? :unsure:
