https://wiki.guildwars2.com/wiki/User:Tanetris/So_You_Want_To_Gear_a_Character has stuff about gear. It's a little bit old but will get you started.https://wiki.guildwars2.com/wiki/User:Gulbasaur/Things_I_Wish_Someone_Told_Me_-_A_new_player_guide#At_level_80 is a guide I wrote with a bit about what to do at 80. For gold, if you have LW S4 E1 with the Istan map (you need Path of Fire to get there), there's a consistent gold-farming community. The meta events drop lots of unidentified gear, which you then stick on the trading post. Rich people then buy the unidentified gear and use magic find boosters to try to get rare stuff from it, basically. I think you need over 600 magic find before it breaks even, so most people just sell it. Istan is chilled out, quite easy and actually relaxing if you know what you're doing, but be aware you'll need a mount from Path of Fire or you'll get left behind. You also get unidentified magic which you use to buy shipments at the docks, which give you crafting a materials to sell for gold. Prices fluctuate but the leather and trophy ones are usually the most profitable. If you don't, the Silverwastes is the next most profitable farm, but I know less about that one. Fractals provide a slow but steady amount of gold in Tier 1. Fractal encryptions drop literal junk, but it's really valuable junk to sell at a vendor and you'll get a couple of gold a pop. As you progress up the tiers, they get harder but you get more gold out of it. At T4, they're very profitable but you need to be skilled enough to do it and that ain't easy. The expansion (HoT & PoF) all have hero point worth ten 'normal' ones and are at level 80. The Living World story content is all pretty good too. They're both pretty good if you haven't explored them already.
