Please do this for yourself, and your client, and for your reputation.
1. Add a 50mm 1.8 to your kit. You have no fast glass, and you'll need fast glass at some point at a wedding. Its cheap, fast, and quality(to a Point). Ditch the 18-55mm, You already have the 18-135mm and no need for it.
2. Scout all the locations ahead of time, and get a shot list from the couple.
3. Practice basic on-camera flash technique, Fill, Bounce, AF-Assist, Etc... It will be Needed.
4. A second body would be highly recommended in case your 60D dies.
All in all, I would keep the couple's expectations low. If you turn out better work than expected, you'll impress them. If you raise they're expectations too high, you'll never meet them.
