I didn't use Pickpocket, but that amount doesn't seem unreasonable. At the end of act one I had a third of the gold you have, and around the same amount of extra equipment and loot. Throughout the act I bought any skills from trainers I thought I would need later, or might eventually try, so could have ended up with more gold.
If you don't buy expensive stuff like charms or (when available) holy water, you may need gold to unlearn skills later if you want to adjust your playing style (the cost to unlearn a skill is proportional to the square of your character's level, up to 50,000 gold).
You do eventually succeed in undoing the soulforging, so the after game BF is just the hero and summoning dolls. If you want to check it out, near the end of the main game you may want to have the DK unlearn all his skills, and invest those points into summoning doll upgrades.
BTW, you need to have your avatar online somewhere in order for others to be able to see it. If your IPS doesn't offer any webspace, check out services like
Photobucket or the suggestions in the topic below.
