1) With regards to shipping, you can tell Amazon to ship \"overnight\". But it costs extra. It would be cheaper to order 2 days ahead of time and use \"2nd day\" delivery.
2) I think the Shart CF expansion adapter is a sled. It is an accessory that snaps on to the Zaurus and makes it bigger, and gives you an extra CF slot. (it also happens to have a battery inside). But if you just want the battery, you should order \"Sharp Lithium Polymer Battery for SL6000L Model# EA-BL09\"
3) With regards to bluetooth, most people seem to recommend the Socket card. On Amazon, it\'s called \"Socket Communications Bluetooth Connection Kit\"
4) There\'s lots of choices for keyboards. Browse the forum here and you\'\'ll see a lot of reviews and comparisons.
