I have no problem believing the valve cover gaskets are leaking. That would account for minor oil drippiness, and are a trivial repair once you're already doing t-belt. I still believe the valve stem seals are leaking, though. The other symptoms, apart from the dripping, match exactly, and leaky valve cover gaskets would not account for those symptoms.
On the plus side plenty of engines go 100k miles on leaky valve stem seals. I see them every day. It's just not a big deal, all things considered. The toughest part of it is passing emissions, but I don't forsee a problem there since there is no visible smoke. A tiny bit of oil won't raise HC enough to matter.
