No, and they probably never will since The Simpsons is not always kid-oriented. You could always make your own Simpson's LEGO sets though.
No. Unfortunately Lego didn't make a Ghostbusters set. Definitely a good idea though.

Yes on Lego.com there is Lego Desgin by me.Download it for free and make any set you can think of.
Yep
As of March this year, Lego were still in negotiations to obtain a licence to produce The Simpsons sets, so there are no official designs yet and sites that were showing Simpsons designs have been taken down. The only way may be to make up one's own template until the licence is hopefully obtained in early 2014.
There is not a Lego roller coaster in production by Lego right now, but there may have been a roller coaster set that was discontinued. After looking on multiple websites (eBay, Amazon, ect.) there is not (and never has been) a Lego roller coaster set. I do hope they make one though!!!
The Lego basketball set is long gone from Lego.com. Instead, buy it from eBay or amazon. The set will be very expensive though because of its' rarity.
You can buy a Lego skate park set and build it from a kit
