What I'd add to Squirrel's list, is the "easiest" way to get yourself from 30-32, and then 34
Strikes and the Crucible
Strikes and Crucible matches reward vanguard marks and crucible marks, respectively, these can be turned in at the appropriate vendor for armor (and weapons), as long as you're level 3 on both. You're capped at earning only a certain amount per week, but between the two of them, you'll be able to purchase 3 pieces of new armor that have the new level of 32. The 4th piece of armor you'll be wearing should be exotic, which can be increased to the highest light level possible through the use of an exotic shard (purchased from Xur, or received by breaking down a piece of exotic armor or weapon).
Once that is done, you'll be at level 32.5. From here, you have a few choices:
1. Do the level 32 Prison of Elders, which will give you an "armor core", which will allow you to purchase a level 34 piece of armor from Variks. It rotates weekly, so be careful to consider what piece you want/need and look at the stats. Up until this point, all the armor has had stats that were strength only, obviously this changes how your guardian reacts in certain situations.
2. Hope for an etheric light drop in the Nightfall, that allows you to make any piece of armor (or weapon) have the max allowed stats. Etheric light also drops from the level 34 and 35 Prison of Elders, but it's hard to get through those until you're actually 34. If you use the purchased armor from #1
, you'll probably want to use the etheric light to upgrade armor that more suitably rounds out your disipline/intellect/strength as you see fit.
Once I got an etheric light from PoE, I upgraded armor I got from the Vault of Glass, so my main character has very even numbers (slight edge to strength). Of course, as I continue to run PoE, this will change too. In a sense, they've made it a bit easier to reach max light level, but they've given more of a focus on having armor stats that suit you as an individual player.
