Well the scoundrel is the hardest class to stay at a low level with. You will probably find the Arena on Taris very difficult against Twitch and Bendak, it might also be a good idea to use range more as a rogue - as light armor does not have the best resistance to vibroblades. Make sure you have ample shields, stims, medpacks and grenades. Scout areas with a stealth field generator and place mines at choke points. Stick with Carth and Zaalbaar and make the best of their combat strengths.
