On my break at work so I'll also add a few tips.
1) Dismantle double class weapons lower than your level if you have one better, but always keep one of each weapon and elemental type (void, arc, solar). You need to be diverse and these weekly and nightfall strikes have modifiers that make certain elements more effective and some less effective. Good to have a few of each, but also keep different types of weapons per class as some or better for certain situations. An assault rifle isn't going to be as scout rifle just because your on a larger map, and a shotgun isn't gonna be much help during ma y strikes. STAY VERSATILE.
2) Don't waste glimmer on useless things like engrams packs. Rares become common enough that wasting glimmer on random engrams is useless. Save your glimmer, you'll need it. I used to keep a 8k stack then I needed over 13k glimmer for a bounty and I was pretty much s brewed having to grind out with no open bounties.
3) Keep all your resources, this is extremely important. DO NOT turn them in for vanguard and glimmer. They're used to upgrade legendary and exotic weapons.
4) Make sure you turn in your bounties! This unimportant because you always have a chance to get an exotic bounty which will reward your with an exotic weapon or gear! They won't give you an engrams so this is basically an almost free guaranteed exotic given after a 3 part bounty.
5) Always walk over enemies and bosses as you may miss rare resources and rare drops. They drop cash items (house banners etc.) But also drop important upgrade resources that I'm still struggling to get even at level 26. They're hard to see and if you miss them that's it. They always drop from an enemies body, usually a boss but occasionally a mob will drop them as well.
6) Make use of them travelling merchants, one comes on the weekends Friday - Sunday depending on time zone and sits across from the crucible vanguard. The other has yet to come but it will be a female assassin called the Queens "Emissary" and will sell rare and legendary weapons for glimmer.
Will add more later.
