OK, decided to look into this.
There are no nice, neat tables that I can find. That said, the actual information does appear to be available, excepting for the Wu Jen.
Complete Adventurer is the most straight-forward: it’s included in each class’s entry as Starting Gold.
Complete Warrior neglected starting wealth entirely, but it’s included in the official Errata. Since the Errata is free, I think it’s safe to reproduce that here:
Hexblade: 6d4×10 gp
Samurai: 2d4×10 gp
Swashbuckler: 6d4×10 gp
It’s always a good idea to check the Errata. Wizards has made some hilarious mistakes (my favorite is when they neglected to include any DCs at all in Tome of Magic for an entire type of Truenaming check), so the Errata is good to know.
For Complete Arcane, I can’t find any direct note of the starting wealth, and it doesn’t appear to be in the Errata. However, the Warlock and Warmage “Starting Packages” each have starting money in addition to equipment. I believe the rule is, you take the Starting Package’s starting money after items, and multiply it by 10. The Wu Jen doesn’t have a Starting Package that I can see, however.
Complete Divine is like Complete Arcane, but all of the classes have a Starting Package.
Weird Page on Wizards’ Website
I just found this page, which, among other things, has this:
Q: The Mark of Heroes Campaign Standards Table CS—2 has no entry for artificers’ starting gold. My guess is 200 gp, as artificers get 5d4 x10 starting gold (Eberron Campaign Setting page 33), and it seems that characters get the maximum starting gold for their class. Is this right?
A: Yes it is. In fact that’s true for all the other classes not currently listed on Table CS—2. Of course this is extremely difficult to determine for classes from most of the “Complete” books, because the random starting gold for all but the scout class were omitted. For ease, here is the complete list of starting gold for the artificer class and the classes unlocked by Campaign Cards.
CLASS | STARTING GOLD
Artificer | 200 gp
Favored Soul | 200 gp
Psion | 120 gp
Psychic Warrior| 200 gp
Scout | 200 gp
Soulknife | 200 gp
Swashbuckler | 200 gp
Warmage | 120 gp
Wilder | 160 gp
(omitted: some asterisks indicating some details relevant only to the “Mark of Heroes” campaign)
Since for this “Mark of Heroes” campaign, everyone gets maximum gold, 200 gp seems to be 5d4×10 gp, 160 gp is 4d4×10 gp, and 120 gp is 3d4×10 gp.
Maybe that seems “more official” but since this page is for some weird product (cards to “unlock” races and classes?) that I’ve never heard of, I’m not sure what to make of it.
Upkeep is already priced into the wealth by level guidelines, and this is part of the reason for discrepancies between those guidelines and a straight extrapolation from random treasure tables.
From Dungeon Master’s Guide pg. 54:
As such, if characters are kept roughly to the wealth by level guidelines, then it can be assumed that they are paying for their own upkeep. The numbers are designed such that you don’t need to track incidental costs associated with upkeep.
Put another way, the wealth by level guidelines are specifically wealth—they represent how much value a character’s useful, valuable equipment and gear should be worth to that character. It can and should fluctuate quite a bit around the listed value, of course, but it should generally be the target, and if you’re on target, things are going well (at least, according to the Dungeon Master’s Guide).
The Dungeon Master’s Guide does list an optional upkeep rule on page 130, but this is really only if you want more emphasis in your game on the subject of upkeep. Since you are explicitly looking to limit the need to track these things, I recommend simply using the wealth by level guidelines. Things like lodging and meals can be ignored unless you want to roleplay a particular night or meal, and even then the costs can be abstracted—or even waived in-character, as a form of non-monetary reward.
