A lot of these relate to his BC though. The only issues that concern me in any way are the ones mentioned in the various lawsuits since, for obvious reasons, questions thought up here or elsewhere are not going to be answered by Obama if they aren't in a lawsuit that makes it through the discovery process.
Obama/Dunham marriage license -- Not released
Soetoro/Dunham marriage license -- Not released
I wasn't aware that these were being asked for in any of the lawsuits, and can't imagine why they would be.
Fransiskus Assisi School School application -- Released
Punahou School records -- Not released
These are asked for because they should list citizenship.
Selective Service Registration -- Released – Proven Counterfeit
This is a separate issue from the lawsuits, and if he really didn't register and if the document that was released really is a forgery then he committed a crime and should be sentenced appropriately regardless if he's the president-elect or not.
Occidental College records -- Not released
These have been asked for the same reason as his other school records.
Passport (Pakistan) -- Not released
Pertains to ctizenship. (Entering a country that Americans were not permitted to enter.)
Columbia College records -- Not released
Same as for Occidental.
Columbia thesis -- Not released
Not to sure about this one, but I would imagine there is curiosity about it due to his wife's thesis. Birds of a feather and all that.
Harvard College records -- Not released
Same as for the other two college records.
Harvard Law Review articles -- None (maybe 1, Not Signed)
Seems kind of odd to not have any of these anywhere since he was the president of the HLR.. Not too sure why these would be asked for though.
Baptism certificate -- None
Perhaps to disprove his claims of being Christian? I don't think everyone gets one though, so I'm not sure what good it would do.
Medical records -- Not released
Bush's medical history
Clinton's medical history
There are medical records for every president we have had on that site. Of course I can't vouch for the accuracy, I'm not a doctor and am not over 200 years old so I haven't personally given physicals to any of the presidents.
Illinois State Senate records -- None (Locked up to prohibit public view)
Illinois State Senate schedule -- Lost (All other Illinois state senators' records are intact)
Well now that's just silly, took me two seconds to find them here.
Law practice client list -- Not released
I think they are asking because he may have represented people who then supported his candidacy with large donations which leads to a conflict of interest. I don't know that this has been requested in any of the lawsuits though.
University of Chicago scholarly articles -- None
I'm not sure why these are being asked for either. Perhaps for the same reason as his thesis?
..............
Overall, I think that the main reason there are so many questions about him, aside from the BC issue, is that very few outside of Illinois had heard of him before and so he seemingly came from nowhere and is now the president elect. He spent a very short period of time in the US senate and hasn't really proven himself.
The lawsuits should be in the MSM, these are serious allegations and should not be left in the dark corners of conspiracy sites. The issues brought forth in the lawsuits need to be settled once and for all, not swept under the rug. A lot of people have a hard enough time trusting the government as it is, something like this needs to be taken care of not left to fester.
Exactly four years ago, I said, "I hope he runs in 2008. I'd vote for him..." Now, just because you had your head in a hole
somewhere and didn't know who he was doesn't mean he "just came out of nowhere". 
But I'm not at all suprised.
