Firstly, onine relationships can be very different from offline ones. Been in one of each, so my direct knowledge is limited, but plenty of observation time for the offline ones, and some of the other, though that was limited by the two-dimensional nature of the intarweb. Is there a specific reason you'd be going for an online one? Difficulty with people offline? Less desire for that kind of thing?
Second, why do you feel the need for preparation? Just worried you'll flub it up? If its forum-based, then you don't have to worry about the initial questions having some sort of time limit. That, and preparing in advance could cause your answers to sound very stiff and, well, planned. That may not be taken well. If you can answer as the questions come, without having a script, so to speak, it may not come off as smoothly, but that's ok. People don't want a carefully refined, "sanitized" response most of the time. Not only that, but the way you wrote that makes it sound like you want to "improve" upon any answers you may have as well. Honesty is important, and if you start off being dishonest, that starts things off on the wrong foot.
That being said, some questions I could think of would be:
What your interests are
What you like to do in your free time
What you look like (people can pretend all they want that this has zero value. I'm not saying it should matter all that much, but even I catch myself noting such things. That irritates me at times.)
Where you live / grew up
What kind of family you have
Any brothers / sisters
Have you been in a relationship before (possibly, not sure, guessing with this one.)
That's all I can think of for now, I've got to go meet family for dinner, but once I get back I'll see if I've thought of any more. And please don't take it that I'm trying to attack your motives, I have no clue what they are, they could be completely harmless, and it could be that you simply want to answer the questions well and not flub them up due to stress from the pressure, or something along those lines. Just wanted to take care of any possibility I could think of.

That could even be what's running through your head. I just want to make sure you don't take what I've said in a negative way, that's not the intent.
