I'm not sure about the warranty question; you might well have to return it to the UK or Spain if it went wrong (I imagine Spain would be a lot easier for you). But iPads seem pretty reliable - I honestly can't remember seeing anyone here report problems.
Yes, the iPod and iPhone are sold here, but not the iPad. Apple won't stop me from using the iTunes Store just because I'm using an iPad which they didn't release here? There's no risk of some sort of ban?
