I see Guy Kawasaki the Mac Marketing genius and original evangelist has updated his LinkedIn tips recently to include Ten Ways to Use LinkedIn to Find a Job.
My own Linked-In tips should be some place easy to reference and update instead of cut and paste, so -
Updates
Whether you're uploading your address book as a CSV or you're just inviting people you've met elsewhere - if there is any doubt that they'll remember you (for example if you're not related to them, and you don't hang out with them more often than once a month); tell them who you are. For example:
I hope you'll remember me. We met at <specific event> in <location>, <date or month, year as appropriate> and we spoke about <this> and <that>... One of my key projects is <this other thing>
Most certainly don't just use the default invite with no explanation of who you are; and don't say "we met at that conference" without saying which conference it is. Many people go to more than one conference a year; and sometimes more than one conference in the same month. They could have met you at any.
To make sure you make a worthwhile connection, tell the person who you are and why they should care.
When uploading all of your address book contacts, also make sure that you're not asking to link to people who you have no real connection with. All sorts of people end up in address books; but do you really want to add your friend's spouse's aunty just because she emailed you the recipe she used for the wedding cake and you replied to thank her?

Great points, gread follow-up!
Yes, I do not advocate inviting everyone you ever saw a CC: to! However, it's simpler to upload the whole list and see who's already there than sort through first. Unlike some services, LinkedIn doesn't invite everyone you upload automatically, inviting people to muce from your Imported Contacts tab to being a Connection is under your control.
