to 1. Yeah, you could say that. You could also say that purple elephants flew in and blocked the vacuuum, eating and defecating Plo and the clones out into space. If the episode was well written such a mechanism would have been shown, instead of Plo and the clones magically appearing out in space while one officer sits in the pod.
I'd argue that, since we've seen escape pods in ANH, ROTS, and in Rising Malevolence and we've seen how people enter pods (via simple door mechanism) the leeway for such an apparatus is slim.
To 2. We saw clones die in space when their pod was crushed. Thus, i felt the other ones should have gone too.
This was later expanded on in Downfall of a Droid, where Alpha Rex and the other were shooting on AT-TEs form the planetary rings so, it seems like the series canon is sayin g more that suits are sealable (which is still against movie canon and all other EU to my knowledge), but I'm asking more for consistancy in the show.
I dunno, I feel all this is really being blown out of proportion.

Meh, might be a slight inconsistency. Though, I don't really see a reason why it couldn't be not seen. I agree with you actually though, I recall also thinking "Hmm, that's odd"...
But, as you rightly pointed out, they had an open helmet. Though, we actually didn't see them die due to being in space that is just an assumption...I like to think they were perfectly fine and got picked up by a passing Jedi later in the battle.
