I'm also in a semi-hardcore guild and we've set 635 as ilvl target. Crafting/CM/Salvage Yard/Missions got most of us close to 640 ilvl in fact.
Regarding progression our target is normal without the last boss as we'll be going 30 man and he might scale up more then we can manage right now, heroic as far as we can go. I hope 3 bosses on heroic for week one. Everything above that is bonus, but not progressing heroic won't be bad since we're using this time to select 20 raiders for mythic out of the almost 40 available right now.
As a raiding guild you should expect queues first of all on high pop servers.
