Let battery run down all the way before recharging?

The touch doesn't come with any real instructions, just a quickstart guide, so it's kinda hard to know whether you should let the battery run down before syncing it aka charging it.

Also there's the conundrum that if you want to sync files you'll also be charging it so if the battery hasn't run down, you'll be charging it before it really needs it and that might shorten the charge capacity over the long term right?

DO NOT let your Lithium Ion battery drain to zero. This will only deteriorate the battery's life cycle. Lithium Ion batteries should never be "deep cycled." This is a concept left over from old Nickel Cadmium batteries, but does not apply to Lithium Ion batteries. Draining your LiIon battery to 0 before you recharge to preserve the battery's life cycle is a myth. Read more about the chemistry behind the two battery technologies here:

http://www.batteryuniversity.com/parttwo-34.htm

" Avoid frequent full discharges because this puts additional strain on the battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.)"

...And there's more from wikipedia:

"Unlike Ni-Cd batteries, lithium-ion batteries should be charged early and often. However, if they are not used for a long time, they should be brought to a charge level of around 40% - 60%. Lithium-ion batteries should never be "deep-cycled" like Ni-Cd batteries.[7]

Lithium-ion batteries should never be depleted to below their minimum voltage, 2.4v to 3.0v."


...And finally, from Apple's own website:

"Lithium-ion batteries pack in a higher power density than nickel-based batteries. This gives you a longer battery life in a lighter package, as lithium is the lightest metal. You can also recharge a lithium-ion battery whenever convenient, without the full charge or discharge cycle necessary to keep nickel-based batteries at peak performance. (Over time, crystals build up in nickel-based batteries and prevent you from charging them completely, necessitating an inconvenient full discharge.)"

the only problem with your logic is that the iPod touch doesn't use Lithium Ions, but rather Lithium Polymer batteries. Dunno what difference it makes though.

Your confused. Lithium Polymer is aka Lithium Ion Polymer. Same ions held in a different state.
