I'm playing a stealth character as well — level 41, wearing one +30% Sneak pendant, Sneak skill just hit 90, perk line up to Silence with only 2/5 points spent on the first perk (+5% per perk? No thanks, Bethesda). NPCs generally only notice me if they're very perceptive, it's broad daylight outside or I'm right up in their face.
Are you on the PC? Edit: Ah yeah, you are. If so, you can use the console (UESP page http://uesp.net/wiki/Skyrim:Console) to temporarily lower your skill level and see if that changes anything. Or it could be a bug introduced by the worst patch in computer gaming history.
