I need some help or views regarding obamacare for TPS recipients.

Since the enrollment period for obamacare is over for 2015, do we qualify for the Special Enrollment Period for gaining "lawful presence in the U.S." status?
I've been out of status. If possible I want to buy the Gold or Platinum plan under obamacare and take care of some lingring health problems. That way I only have to pay higher monthly premium for the rest of this year instead of the whole of 2016. But, since I haven't paid taxes (i.e. my income is $ 0) can I even buy bronze or silver plan?
Do you have to make at least $11,670 (for a single individual) to be able to buy insurance at all? Or is that only the limit for government assisted low premium? I just want to be able to buy gold or platinum plan and am not necessarily looking for government assistance.
Anybody with more knowledge about health insurance or obamacare, please share your knowledge. If you have any suggestions or views to share please feel free. Your thoughts would be much appreciated.
