Yes, once u have completed the game u unlock Legendary Mod, at this point if u want play on normal yet, just choose the level u want start, and hit the Green shield instead of the Red One.

Complete the previous quest and win gods offerings. Then use it for find equip at least rare (blue). Farm stages for reagents and up ur equip. Learn the cyclop patterns too. Try stay behind him, block his attacks and use pots when necessary. You have done.
Yeah, sorry i couldn't help u a lot. I've just started the Mage, so i'm not an expert. I'm not sure about, but i guess at highest levels in legendary mode bosses you can drop special weapons, but the rate will be very very very low. For the ring and neck, if i remember correctly the best choices are Vulture and Berserk.…
Being part of a guild it's not necessary. But could be helpful through VP Tournament (Guild prizes). And if u have friends in-game, is even better be all in the same chat everytime :)
I'm agree at all. I've a third suggestion about selling. Why don't give the chance to select 2-more items at once to sell? It's quite boring keep press Sell, ok, sell, ok, sell ok etc, when u have lot of green/white equip to sell.
