Keep them inside while they are in bloom. After they finish blooming, take them outside so that they can benefit from the cooler temps and get ready to bloom again next time.
Post a photo if you want repot advice. Cyms like to be mostly root bound, so if they are crowded and doing fine, leave them alone. If there is significant die out inside the pot, It is time to up pot them or divide them into two plants and repot.
