Just what's been said already mate, and it's obviously had a good spray etc. to get all the salt and road grime off it?
Depending on how long you are storing it I would think about giving it a roll out and maybe a short run round the block every few weeks to get it all up to temperature and keep things free, and clean up the discs. Alternatively give the discs a good wipe with oil and keep an eye on them.
Basically just keep everything clean, don't leave the handbrake on, and don't let it think it's staying there forever! Good opportunity to tinker with a few bits and bobs yourself if you feel like it.
Cheers.
