Wedding photography is one of the toughest assignments you will undertake. I'm the first to say it is more about the photographer than the equipment but in this case your gear is probably not up to the task. You will be asked to shoot in all kinds of environments. In a dark church which does not allow flash, photos your gear will not handle the high iso conditions. And I'm assuming you have just one camera body. What will you do if the camera dies? You can't very well expect the bride to be happy when you tell her "sorry, no more photos today".
You really need faster glass and probably two stronger speedlights as well as a second body and extra batteries etc. Can good shots be had with your equipment? Yes. Will it handle ALL of the environments you will encounter? No. I suggest you attend some weddings and practice with your gear. That way you will find out for yourself what you need to add / change. Perhaps find someone who cannot afford a photographer and offer the shoot for free to get experience.
Don't let my comments discourage you. Continue to research and
practice and go after your desires.
