Well the best lenses in my eyes are ones that you use all available light, under the huge situations you will face. If you are shooting morning till late at night you need lenses to deal with these situations. If you are being serious about wedding photography you cannot not use a flash. Even if you are in good light you still get shadows casting around the eyes and face and they need to be filled with a little flash. A 580 with a gary fong light sphere does an amazing job (like having a studio! it bounces off the ceiling and has a cap which bounces back into the 360deg bowl giving extremely flattering light. As a wedding photographer you cannot choose the time, light and type of day unfortunately they are all abnormalities. Obviously you wont use flash all the time but it is a must in a wedding kit.
Basically you need to think of the type of situations you will face, your camera and your budget.
Wide angle for large groupes, tight venues etc
standard lens to be suit many situations
prime for those beautiful portraits and small details
telephoto to pick out people, for those journalistic shots
If you had a 5D or a 1 series i would say yes go for your choices but seen as tho you are using a crop camera all of the lenses you are specifying you have to add the 1.6x crop factor and tbh the high end EF-S lenses will be just as good a and cheaper just without the weather sealing.
Also the widest lens you have is 40mm (24-70) on a crop camera and believe me, you will fit nothing in the frame with that, you need something alot wider like 17-24mm to fit the group shots or if you are in a confined venue where space isnt abundant.
The kit i would buy is :-
EF-S 17-55mm F2.8 IS
EF 24mm (because it works out about 40mm) if not then the 50mm F1.4
EF 70-200mm F2.8 IS (not the brand new one but the first IS version to save money) The 2.8 rather than the F4 because it picks up people out of crowds beautifully and also is suitable for lower light conditions
580EX with a gary fong light sphere
I would also have a second body always one with a standard lens and the second body with the 70-200mm or one of the other lenses.
Ive been shooting weddings for 5 years now and this kit has always come up top trumps for me. You are effectively covering 10mm-320mm (with the crop) and if thats not enough i also carry a 2x extender. Also i disagree about the flash, yes its nice not to shoot with it but you will never see a professional wedding photographer without one, and the results show. Most of the time if you learn how to use it properly its almost unrecognisable.
Hope this helps
