Gold boost and XP boost are more or less pointless unless you're planning to speedrun the game, since you're supposed to be max level around the end of the campaign and with the boosts you hit it even earlier, which doesn't change much. I'm pretty sure "Tomb Kings" adds some OP stuff, so if you're looking to push builds to their absolute limits you'll need the DLC, unfortunately. It, along with the "Gods Pack" also adds a bunch of new passives, which is arguably the stuff you might be interested in, since they add some build variety and the base game isn't too generous with that. "Tomb Kings" adds a new chapter which is also neat because it takes place in an entirely different location. Witch Hunter is pretty cool as far as classes go, but is only valuable if you're interested in playing him, naturally.
