What to do?

It doesn't mean much actually. It just means that she uses facebook to interact with her closest people, and doesn't like comments. I think you should continue liking her statuses once in awhile, but not every single one.
Liking her statuses is enough for your online interaction with her. People tend to feel happier and please when their statuses get likes.

Now, be careful when you say hi to her at school though, eye contact is a very tricky thing. It can get you disliked by her, and deleted from facebook just like it can make her think that you seem like a nice guy.
I used to like a girl and we were ok on facebook but we pretty much never spoke at school, then one day she looked at me, I was pretty pissed off at the time and gave her a strange look, because I was surprised and I got 'butterflies' in my stomach, and that made me my day, but on the other hand, it made her feel unwanted and got me deleted from facebook, so I suggest you are careful with that. First impression is very important.

Very helpful for my situation, sometimes when it actually comes time to doing something you forget all the basic things that make a difference, and little things like that, i've seen how they can make an impact. I actually did the same thing, then they don't feel like talking to you because they think you keep your distance from them, and then you might go off thinking about what happened. Then you start believing that they don't like you, and you never talk again lol. It's funny how that works, and our mental limitations can stop all the good things from happening.

I think I will just stick to "liking" her statuses until I get a chance to actually see her, and if it's a short time then i'll just make a friendly smile to her. That seems to always make people feel happier, even if its just a smile! psychology is intriguing in that way.

I will stop analysing things though, thats all I need to do, until I get a definite "no" but if theres any questions, then it probably isn't a no in most cases, thats my advice from experience.

I dont think she uses facebook for the profile itself, who knows, maybe she uses it to use the IM for online friends, but I don't know that yet lol. "like" the random status of hers here and there, and maybe i'll get lucky and she will respond She when I see her though, she keeps giving me a smile and I sort of smile back, but both are kind of casual smiles. She doesn't seem like most girls though, so i'm not going to rush in and start talking to her on facebook everyday. Personally i'd rather not be talking only on facebook, but i'll go slow if I decide to say hi and eventually talk to her in person too.
