Wine likes to be kept in dark conditions, away from direct sunlight and not bothered. Constant moving does not do the wine any good - it prefers to be left alone to mature in peace. It doesn't really matter what temperature you keep the wine, so long it is not very hot or very cold. Around 16 degrees centrigrade is fine.
It is generally preferable to store wine on its side, since this will stop the corks from drying out (which then let in the air).
And when you are ready to drink your lovely wine, let it stand upright for a couple of hours and then decant it.
Keeping a record of what wine you have purchased, when you purchased it and how much it is worth, will also help for good cellar organisation. As your collection grows, it is easy to forget what you should be drinking and when. Keeping records helps!
