Not sure if I should repot my orchid ? HELP

[PetitPrince]

Hello!

I have a Phalaenopsis orchid that I bought at the Home Depot on November, 2009. She was in bloom and later on, she naturally shed her flowers and dried her spike little by little all the way down to the bottom, at which point I cut out. Now, I was thinking of repotting her because several roots have grown out of the media (bark) already and are sticking out, above, and around the pieces of bark. This would be the first time I repot her since I bought her back in November. After seeing her roots like that, I thought she was outgrowing her pot, and that she needed to be repotted into a bigger pot. However, right now, she is also beginning to grow a green spike. The spike is still small, but it already reaches a height of approximately 1.2 inches. I am not very savvy about caring for orchids or plants in general, which is why I am not sure whether the buds have already appeared. I see a tiny little green protuberance on it, but I am not sure whether it is really a bud. It seems more like part of the spike itself. But since I read somewhere that one shouldn’t repot the orchid if there are already buds on the spike, I wanted to make sure.

I hope somebody can help me with this by giving me some advice on whether I should repot or wait till the spike blooms and then dies naturally before repotting the orchid. But if I wait, it worries me that it will be way into the summer before I can repot her again, and I understand one should only repot while the weather is not too hot. On the other hand, if she stays too long in a pot that she is already outgrowing, wouldn’t that also be harmful for her? I really would not want her to die. She looks very nice!!! She has one little bottom leaf that is yellowing out, but the rest look very healthy.

I am including a few pictures to illustrate what I am trying to explain.


Thanks to anyone that can help.
