How is Obamacare going to work for families that have expensive workplace health insurance?

I have been searching and searching - maybe someone here can point me to an answer:

Single (never married) Disabled (on SS Disability, NOT SSI) and paying 20% for Blue Shiild. Do not want Medicare (I have enough trouble getting accepted to a new doc without answering “Medicare” to their “What is your insurance?” (which, btw, is a good way to hear what a hang-up sounds like on your new phone).
My medicines are incredibly expensive, and am looking at kidney dialysis/transplant.

Can I get some credit/rebate/whatever to take the edge off the cost while keeping the existing policy?

Blue Shield of California is being tight-lipped about 2014 - just “If the law stands, you may have additional health care options beginning in Jan 2014”.l

I may or may not be eligible for “tax credits” which can be applied independently of taxes to pay part of the premium, correct?

By how much do you suppose the insurance rate will increase for each dollar of “tax credit” they receive? (yes, I"m cynical - comes with age and wisdom).

If the current “interpretation” means the rules seem to directly contradict legislation, I suspect a number of lawsuits will emerge in the near future…
