The 787 was never publically released and given that he is now in university, I imagine a website is the least of his worries. Sorry to be the bearer of bad news.
I'm not 100% sure about what you are asking, however, in response to Question 2, only the scenery that has been downloaded will be updated; no extra scenery tiles are downloaded with the updates.
What aircraft and/or scenery are you using? This can vary FPS quite a bit. EDIT: E.g. LES SAAB 340 and KSFO Tom Curtis package or default aircraft/scenery?
If you have MisterX6's KSFO you can download a version that doesn't have the invisible barrier. The barrier is used for Marginal's traffic plugin I believe.
