Tulips will flower year after year if planted deep enough - 9" - and in soil that isn't waterlogged in winter. Mine out in teh big borders tend to get eaten by rodents in winter but I've had great success with the smaller botanical tulips in other, well drained beds.
Daffodils go on for years, especially if planted deep but may need to be lifted and separated every few years if they get crowded and stop flowering. I've had some in for 12 years now and still flowering strongly each year. paperwhites, grown for indoor displays, are not usually hardy enough to be grown outside.
Hyacinths also repeat flower although forced ones wn't do so well the first year aftre being put in the garden.
Alliums go on for years too.
I don't feed bulbs specifically but I do scatter a general feed on my borders in spring and I do dead head except snowdrops and crocuses and scillas and grape hyacinths and other tiny stuff.
