You can, because both AdminMod and POD-bot 2.6mm are metamod plugins. Hence all you have to do is to put one line in your plugins.ini file for AdminMod, and another line for POD-bot.
The PODbot you've tried must be the old POD-bot 2.5, which was NOT a metamod plugin but a standalone DLL (although there is still a way to get the old POD-bot 2.5 and metamod to work together, but it's a bit of a trick and complicated for beginners).
BTW POD-bot 2.6mm has evolved a lot since POD-bot 2.5, I recommend you to try it asap
