This is a once in a lifetime opportunity. Unfortunately if you don't like sorting through coins it might seem like it would take a lifetime.
If you can't face the prospect of doing it yourself, perhaps you could enlist a local coin club if you let someone have a piece of the action.
Definitely sort by year and mintmark, and get that book that was mentioned. Also look for minting errors like clips and die cracks.
When looking for varieties it is best to look at one year and mint mark at a time. For those years and mint marks that have no varieties they can simply be returned to the bank.
