Keep doing Eris bounty and the missions you will eventually get an urn bounty that gives you 33 light gloves Get vanguard rep rank up to level 2 and buy the boots for 75 vanguard marks Buy the void fang vestments from xur Get a rare helmet with 19/21 light You should be able to do all of that by the end of the weekend. If you do all of that you will have 123 light which will get you to level 30 and to get to level 31 all you need is the raid helmet from vog 30 light or by next week you might have enough for the vanguard helmet.
