tiny Onc. sotoanum arrived w/four spikes - when to repot?

[learning_curve]

I'm a newbie who probably like many learned on grocery store orchids and then got interested in learning more and branching out. I noticed an Onc. sotoanum 'Roy' on sale when I was ordering supplies and decided to try it, but to my surprise it arrived with four spikes covered in buds. It's in the usual 2" plastic pot plants come in and I'm wondering - should I leave it there and see what happens with the buds, or repot? This is my first post and it won't let me include a photo but since arriving the spikes have all gotten new growth and the buds are bigger I'm guessing I should leave it but the little black plastic pot makes it really hard to make sure I'm watering correctly and everything's ok down there. Also, do you usually give the spikes support? They're at about a 45-degree angle right now from the plant base.

Thanks in advance for any advice, this is my first oncidium and I'm committed to keeping it happy For context I live in the Pacific Northwest so warmth and sunshine can be a challenge but I have a very bright apartment with huge windows and my other orchids have been doing well year-round.
