Per point #1: Gateshead is probably a good comparison (community built around a Yeshiva). Gateshead set up a vaad which establishes the price of homes based upon the prices in the neighbouring non Jewish areas.
This ensured:
1. That the yeshiva families would not be priced out by baal habatim
and
2. That people would be less likely to buy as an investment and more likely to buy with intentions of living there.
At this point, however, any idea of setting up such a vaad in Lakewood at this stage would likely fail.
