I would do everything possible to prepare to move out on your own. If you are graduating from college in 2010, you may want to make a goal of moving out totally sometime during that summer, preferably early on. Try to have a good enough of a job so you will not need your parents for assistance. That way, you will be able to blow off all those pukey washtowel studies.
Meanwhile, if your parents need your help or are getting it for free and would otherwise have to pay for it, that is another card to play. As long as you are providing such, room and board would only be a form of payment for it. You should not be obligated to believe what they want you to. You should be able to stay home from those boasting sessions instead of going--focusing on your own work and studies instead. Put away a good chunk of your earnings so you will have enough money to rent or pay a down payment on a house; once you have that, stick that in a safe investment that is going to earn a reasonable interest rate. At this point, anything you can add to it will be a plus.
Now, if at any point your parents try to force you to go to boasting sessions or threaten you with eviction, you are ready to move out permanently. You will now use that money in your savings to pay rent or a down payment. Even if they try to threaten you to keep you from disassociating, you will be ready to move out on short notice. At which point, you should have enough to pay any moving expenses saved up. And, once you are gone on a day's (or three days') notice, your parents are suddenly going to be up sxxx creek without a paddle and have to suddenly find alternate help (that is going to cost them some serious money). At which point, you will not turn back.
I think that step is eventually going to be necessary regardless of religious differences. When people live with their parents long after they turn 18, they usually are prevented from living to the full. You should have a goal of being totally free by the first of 2011--or shortly after. For sure, people should be independent by the time they reach about 25. Otherwise, they are going to have trouble making their own decisions and living to their full potential.
