For newer versions, what's on this forum is what we have. Now, let me offer some guidance.
First, I'd like to say that gold is relatively easy to come by in this game, either my picking up and selling rares, selling socketed throwing weapons (throwing knives, throwing axes, short spears, glaives, etc.) with any rune in them, finding and selling apples, and I'm sure by other means as well. Once you hit Act II in Hatred, the maximum you can earn by selling goes up substantially, so you should be fine as long as you pick up every rune you find along the way.
Next, let me offer my opinion: half the fun of the game--to me, at least--is theorycrafting new builds. Skim through the documentation which is available on the DOCUMENTATION tab on the top of the screen if you're on PC, mobile you should be able to find it with a google search like "Median XL XVI documentation". There you can find all the information on every item in the game sans realm-only secret Sacred Uniques (SSU) and such, and from that information you can identity what items you want to obtain and what items are good for your build. However, figuring out what exactly IS good for your build is understandably difficult for newer players, myself included for a long while.
That said, what kind of Barb build are you wanting to make? I'm sure I can give you a few quick pointers (more experienced players, please fact check me) that'll get you started and set you on the right path for your character.
