On a note of what to travel with, I only carry 2 regular salvage kits and 1 identify kit up to Yaks Bend area. The amounts of the salvage out of early level items is not worth the 16gp that the expert salvage kits takes from you per salvage, stick with the 4gp per salvage kits (100gp) till Yaks bend and then it's a good idea to make a list of what you salvage out of certain armors. Some never give up anything worth the expert salvage kit use and there's a website that lists what each armor will give you, I'd suggest locating this and make a copy so you won't waste valuable gold on expert salvages you don't need to.
Once at Yaks bend then carry 1 identify, 1 regular salvage and 1 expert salvage kit with you. Perferably full ones, so if one is pretty certain to deplete on a mission, farming run or whatever, buy an extra one to take it's place. Salvaging while farming allows you to store more items in your inventory and opens more slots up to loot items. Soloing especially will fill up your inventory quickly and you'll end up having to drop items or head back to town.
Be sure and get yourelf (2) runes of holding asap, these will add 5 more slots to your bags. They are expensive to some of the newer players 500gp each but, well worth the price in the long term for 10 more items you can pickup along your quests/missions/farming runs.
Many people rush out of "pre-searing" and that's one of their biggest mistakes. There's good income in pre-searing and lots of things that can be salvaged for materials you will need for your next armor set. I've spent up to level 8 in pre-searing collecting lots of materials and coin with all my characters. It's the best solo area in the game for new people to the game and everything drops something. I enjoyed farming the catacombs the most. And the crawls.
Of course like any other game the futher you get into the game the better the income. So don't expect the get rich quick plan or expect to have everything everyone else has for a good 3 months of hard play. If you're a 14 hour a week average player you're going to make an average income for 14 hours. Of course there are exploits where some players make 1000's of plat an hour, rune hording. dye hording and 105/55 Mo/W builds that exploit solo the underworld and FOW. I hope you are not like those players.

If you are then I'm sorry I helped you with this information.
