By the rules
1) Yes bears endurance give yous a boost
2) There are no rules on what players do or do not know. Thats up to the DM
Level drains are the worst thing ever, the cripple your character in combat and then out of combat you have to pray to the gods of dice that you dont lose a bunch of levels to boot. Level drain mobs are worse thant anything else in the game, because other monsters can only make you lose one level... This is doubley so because almost all level drain effects are touch attack so if the creature get suprize your character can be 1-8 levels down before he even gets to act.
Honestly Id give the players anything they can reasonably argue. if nothing else your work as a DM will be twice as hard if the player are suddenly 6/7 levels apart becaus the the fighter lost 6 levels and the mage 1 and the cleric 3 and so on. They ARE fantasy adventurers in a world where this is all pretty well documented.
Thats just my 2c as a player/part time DM
