Public events are great for all the gear, but even if it's not good just break it all down and that gives you materials for the Gunsmith, and you'll also get planetary materials for the vendor on that planet. Strikes are good as well because of the Vanguard tokens. Crucible seems to be giving away some stuff as well. At 233 you should be able to do the Flashpoint and that's where I would focus your energy to get a nice boost. Good luck and take your time, have fun... don't stress about "power level" too much and enjoy the game. The raid isn't going anywhere and people will be running it constantly for the next few weeks.
