Apologies if I double post before someone could answer, but this is continuing my questions.

3. Following from 1., is there anything I can do out in the field to catch up from what I missed? I'm sure I was supposed to pick up on something with Topaz Carby besides just summoning him for when I need a tank, but that fight's been Echo'd (as I mentioned before) and gone. The sad thing is, I never run into problems out in the field since it's just me and Carbuncle to keep track of.

4. This is probably the big thing I'm having issues with. I've noticed that I can't tab to target NPCs. Is there a way to pick out an NPC to heal when they're mobbed together? What about how to find out just how many NPCs there are and which ones are the ones to keep alive? And which ones have hate from which mobs? The more questions I ask the more I feel terrible about all this. Ugh.
