If you think that your plant needs to be repotted - lets say - it is already past 6 months or it is much bigger than the 3 times the pot diameter - do it - otherwise ignore. Some plants are just very vigorous and want to take over the world.

Nah, just remove them, If your plants are still small - do not increase the size of the pot, you can shake the soil off a bit and add some fresh one. If they are still small - give them some special attention - like leach them with a weak fish emulsion. Usually if the roots are getting out - means the root ball is all packed with roots - or if there is not enough water - and they try to reach a drink. How the soil feels on a surface? If it is on a dry side - you can use a thicker wick next time.
