No- your gold total will not decrease. Gold is cumulative and cannot go down

I don't think that's right. You can either accumulate gold or cash it in to upgrade Barbarian Homer/Archer Lisa/Goblin Bart.

No. You only accumulate gold, you don't actually spend it. Upgrading the characters does not decrease your gold in the slightest. Don't be afraid to upgrade your characters.
