Well, the reason you wouldn't switch to the other faction, is that LS/DS doesn't have to do with factions. You are supportive and a huge part of your faction, and do believe in it. but, you may have different ideals and ideas of how things should be done than the leaders of your faction. So a Jedi may think taking a life is worthy of the greater good, but the coucil would disagree. That's more how it works. As for gear, there are LS/DS gear that are the same, but have that different requirement. You may get lucky and get a drop that needs lightside, and you can wear it. You might get the darkside version though, and can't wear it because you are lightside.
