Just replace the bottom bracket, there is no benefit to replacing bearings on a square taper bottom bracket unless they are loose ball and even then I would replace with a sealed cartridge unit. Commuting is some of the roughest riding your bike generally sees for most people, because you are trying to get from home to work and back and usually when you are tired or worn out or stressed or whatever and you get home and you probably don't want to to do maintenance and you may not do it often and sometimes at all. Get a decent quality BB and it will probably be only marginally more expensive than bearings but will end the hassle of having to press in and out those bearings with tools you may not have. The only square taper BB I might consider replacing bearings on is a Phil Wood unit and even then I would rather just have an SKF or IRD Defiant (QB-95) and just have something that lasts and lasts and lasts with easy install (Phil Woods are a little more fiddly not by much and they are very high quality) You shouldn't need to replace a bottom bracket super often unless you are buying cheap stuff or trying to rebuild them constantly.
