cymbidium and winter rest q's

[guppylove1985]

I just picked up a couple cymbidiums, one of which looks like the roots are exploding out of the pot lol. I'm new to orchids, and I've read that some orchids including cyms need a rest period. Does this affect whether or not I should repot now? Can someone explain what my watering schedule should be like for these plants? Thanks!


Also, I got an oncidium 'sharry baby', and I'm just wanting to make sure the bulbs look healthy, since I really don't know myself. Here's a pic of the oncidium.
