Don't do wedding shots until you are ABSOLUTELY 100% confident in your ability, your understanding of your camera, the whole damn shebang. 2 weeks experience is not enough.
It may seem like money for jam, but wedding photography is extremely demanding, and you only have to miss out 1 particular traditional shot that the bride's mum was expecting and she will curse you unto the 7th generation.
If you do agree to do it, you crazy fiend, make sure you have AT LEAST two of everything you need, tripods, REALLY POWERFUL flash guns, cameras or camera backs (maybe even 2 B&W, 2 colour) etc etc
Then google for a list of traditional shot, check up on the venues - church, reception hall, gardens in which to take outdoor shots - but don't forget the (artificial and posed) candids of the bride getting ready, the groom at home looking nervous, and so on.
Make sure your transport is sorted. Get a tick list of the shots you want. Ask bride, groom, bride's mum for special requests. IMPORTANT, check that there will be no professionals in the area - my first set of wedding shots features a bloke with a big tripod, or his burly helper, in nearly every frame. (b@st@rds...)
Good point that - get 1 or 2 helpers. They can grab wanderers from the flock, they can do zone marking, checking that no one has their eyes shut during important and vital large group shots, etc etc.
Have I scared you off yet?
Final point. Check local wedding photographers for their prices. Undercut them - BUT, only by the tiniest margin. You are putting yourself on the line here, and deserve to be rewarded accordingly.
