I'd say your topic was overlooked in huge spam problems.
Go to world database and open player_levelstats table. Thats all you need, you will get to all stats of all race/class combinations on different levels. A few tips:
1. If stats for some level are unknown, stats for the highest level below current one which are found are used. Thats why all level 81+ characters are getting level 80 stats.
2. Do NOT delete stats for level 1. Never, ever. It will cause your server to be unable to run, and it will keep crashing on startup. This is caused by function mentioned above, which is a little bit silly in its design, but whatever. #HateTC2
Apart from these two details, table is pretty straightforward.
There is also player_classlevelstats table. That contains only base mana and base hp for class and level combinations (so this one is not related to races, unlike levelstats one).
