Don't pick at any body orifaces while in her presence. Do not break wind or burp. Don't talk foul. Don't blow your nose without a tissue. Don't make rude jokes. In-depth discussion of these bodily functions is just as taboo as the functions themselves.
Most importantly, start early finding your self-confidence and ditching your insecurities. Women find that these make men unattractive, as they are signs of emotional weakness. Don't overdo it though, secure does not mean bully, stuck-up, or asshole.
Until you've married her, you can live without her. You don't have to *say* this, but if you keep it in your mind, you won't do the worst thing - which is obsess over her. Most importantly, she won't have you under her thumb. This will drive her wild. The more independent you are, the more they want you, friend.
[edit] Oh, and it has to be said. Find your physical happiness and balance. Work out. Run. Play sports. Eat right. These will add to your overall confidence, helping you with the security part. Plus, there is absolutely nothing wrong with working to look your personal best.
