In addition to what Ladybird has said, crocus and daffs are pretty foolproof - just plant at the correct depth. Tulips need good drainage, so use a nice gritty compost for those.
It's normally recommended to plant tulips later in the year when it's colder, to avoid the viruses, so if you're buying some in the next few weeks, you may want to keep them somewhere colder for a month or so. I usually just plant them and keep them in a shady spot and have never had any issues.
