I accidently added too much potassium metabisulfite (1/4 tsp to about 3 gallons of must). After letting it sit for 24 hours and then adding yeast, the yeast took and it was bubbling happily after 24 hours. I'm now 4 days into primary and it's still bubbling very happily. Will the excess sulfites still have an effect on the end product?

No, the sulfite will dissipate during the fermentation period. You will end up with some bound sulfite, which may affect MLF if you plan to do that.
