Growing hyacinths is relatively easy - it's keeping them in good growth to flower next year which takes more care. Remember that in the 50's a common way to grow hyacinths indoors was in a hyacinth vase - a glass jar with a constriction. You filled the jar with water, and sat the bulb on the constriction. The hyacinth put roots down into the water, and used its own stock of nutrients to produce the flower and first leaves.

Therefore, I'd assume your chance of overwatering is slim provided you don't keep it waterlogged above the level of the base of the bulb. So try sitting the pot in a bowl of water (perhaps with a tiny bit of washing up liquid added) for a few hours. Balance a weight on the pot if it tries to float. Once the compost has wetted itself, keep it moist but not wringing wet.

After the hyacinths have finished flowering, continue to water and start feeding them. I'm not sure they're really worth growing on - they don't come back as well net year, they tend instead to look like rather brash bluebells. I tend to stick them in an out-of-the way bit of garden (of course, they might do better in a prime spot!)

As far as other bulbs go - daffs are easy, as are crocuses, but crocuses will give up any attempt to flower if they're kept too warm too soon - keep them outside, then bring them in when the flowers re ready to open.
