The best way to draft Zendikar block is to open all your Zendikar/Worldwake packs without drafting them, then draft triple RoE. Zen/Zen/Worldwake is one of the most hated draft formats of all time because the optimal strategy is to pick aggressive 2 drops over anything else. Triple RoE, on the other hand, is among the best draft formats of all time.
The best thing you could do with your packs triple Rise of the Eldrazi drafts. The worst thing you could do with your packs is squander your packs on some unholy mix of RoE and Zendikar in the same draft.
Similarly, Shadowmoor block is best enjoyed without the Eventide packs -- even the lead designer of Eventide has admitted that Eventide messed with Shadowmoor draft too much and hurt the draft format. Triple Eventide is also notoriously bad, mostly due to the mimics but also because there's nothing good about it. Go triple Shadowmoor.
For Lorwyn, conventional wisdom says go Lorwyn/Lorwyn/Morningtide because that's the official format and it's a good format and you have the packs. That said, triple Lorwyn is more popular by a small margin (you can make Elvish Handservant decks), so you might want to go triple Lorwyn. I've played Morningtide sealed before and found it to be fun (I had 2 Bitterblossoms, of course I found it fun) but prowl decks are probably overpowered in triple Morningtide. I'd say you should go Lorwyn/Lorwyn/Morningtide to get the most out of your packs, but also consider 3xLorwyn.
