Excellent video on how to prepare your coins for the fork:
https://www.youtube.com/watch?v=S-raVquA_zQOnly thing I'd change, for extra security, is waiting until after you've move the coins 'out' of the temp wallet and back to the main wallet (post-fork) to extract your keys.- YES, this. It's absolutely awesome that people are making vids to demonstrate, but remember to please not even extract that key before moving the coins away to the safe wallet. You don't even need to SEE that key on the screen before then (to protect you in case your machine's infected with malware that can screenshot or steal your clipboard).
And confirmed on the 1.85->18.5

Even if you have 0.00000001 LTC, you'll end up with 0.0000001 LCC.
