I can't add much, but on #1, If you max out the rep, there ARE yellow titles that the altars give. Some may be helpful, some not. So far with my Demonologist, I've stuck with the Roaring Maw title (+10% crit and mcrit).
I don't do pvp myself, but I wanted to say sorry that you ran into people like that. I don't care enough about pvp to put up with that, but if I did, I'd just ignore them.
The daily quests are from the blinking thumbs up next to the mini map, above the mail button, yes.
With forting, you can generally get by with SS until +9, then need MFIs after that. You don't want failures after +9 because the item will disappear, which is why people use the MFIs. For wizard, you'll want to get m-crit, not just crit. From what I understand, the best stones to get are the +8% mcrit damage stones, but those are VERY expensive now, since they were taken out of the oclay table.
