Tips? OK, here's some:
Get some of that PDA screen-cover. That's very transparent. Now put it over the screen(only the screen). Put the iPod back-side up and use a sharp knife to cut along the edge of the iPod, to get rid of the unnececary cover.
Now your screen won't scratch, you got good visability still(big problem with expensive iPod covers) and the shape is the same.
When the ear-buds don't perform any more, get some good headphones. It's worth it, listening to music with real speakers...
Highlight all your music in iTunes and drag-drop it over to the iPod at the same time, just to admire the speed of FireWire.
Always keep the charger near-by when on a trip, having a flat battery before a 6-hour bus-ride is a pain...
Don't leave connected to Mac while Mac is asleep, that'll drain the bettery rather than charge it (did that 2 days ago)
Show it to EVERYONE, and let them touch...it has an amazing "WOW!"-factor and they will all envy you
