Those are the two main websites people use, when looking for builds. I can tell you that for your Engi, if following the, “Meta” is your thing, you would use a set of Viper’s Gear (Condi damage/duration.) and for your Guardian, a set of Berserker’s. Viper’s is only attainable through crafting, achievements, and with the new LS3 maps (Trinkets.) Also it is VERY expensive.
As for gearing up, depending on how much gold you have, or if you buy gems, you may want to look into doing dungeons for dungeon gear, you can get rares/exotics from them, not vipers, but rampagers (Cheap alternative until you get vipers.) and berserkers is a very common set.
I would also recommend that until you feel like, “Hey this is the toon/build for me”, stick to using Rare quality gear, you can get a feel for it, and see if it’s, “For you”. Because if you’re anything like me, I prefer having fun, over what is seen as, “Meta”.
Also for making money, there are plenty YouTube videos on what to farm, and where to farm, ect.
If you have ANY more questions, feel free to mail me in-game, or whisper me if I am online.
Good luck, and have fun!
