Personally I find it faster to trade an NPC some gil than to talk to them, wait for the box to pop, and then choose to pay ... but I'm weird like that.
As for the camera spinning while dead, just like when being alive, you can be in places where the camera gets stuck and you more or less have to move yourself in order to spin it properly. (And when dead, you can't do so, so you're screwed.) However, in many cases you can get around "sticking points" by moving the camera up or down, or trying to rotate it in the opposite direction.
(Oh and as an fyi to anyone who doesn't know how to rotate the camera while dead or while some other screen or something is up that occupies normal arrow key usage: shift + arrow keys. You can also move your mouse to the edge of the screen if you prefer, but shift + arrow keys offers finer control.)
I do agree with most of the stuff in this topic, it's really just needless - it's a bit of an interesting touch the first time you encounter it, but it's little more than a tiresome obnoxiousness after playing for years:
Not being able to search while dead.
Having to talk to an NPC for rent-a-room/mog house.
Being able to enter your mog house without your moogle there but having to zone out and talk to said NPC to get the moogle there so the mog house is useful for anything.
How your moogle can't warp to your mog house to get items out of furniture storage, but is quite capable of warping to Whitegate for a mog locker or warping to your mog house to check your plants.
Taru speech impediments.
