with that kit i'd have the 50-150 on the camera all day...
The 50-150. is going to be your bread and butter. It's really hard to catch a facial expression or feel close to the action with a 17-55mm. The only time I would use that is for large groups if you can't get far enough back or for a few establishing shots during the ceremony.
I have a 17-55, love it. But when I shoot weddings, it doesn't see much action.
Sorry, but this is really bad advice, you should be working mainly in the 50mm full frame range (around 30mm on your 60d).
I don't mean any offence, but most of the folks on here are not pro wedding photographers, you might be better asking this question on a forum that is aimed more at that sort of person.
More importantly, you need a spare body.
IMHO the people who has adviced here, myself included have not pretended to be something they are not:) I looked at your pictures, and they are great.
I think the case as it was with me, many people are short on money with all the expenses for a wedding, and in that situation they tend to ask friends who they know shoot pictures more or less well to do it as a favour. It is not because we want to do it, but rather out of an obligation to friends. Alcohol, food, music and other things are expensive, but soon forgotten, while the pictures who will live on is the place many unfortunately feel it's okay to save money...
I agree, I don't have a beef with people giving advice. It's just that TBH this forum is mainly occupied by photo enthusiasts, rather than experienced wedding photographers. Nothing wrong with that, but maybe not the best place to get wedding photography advice, I would suggest maybe the digital grin wedding forum as a good friendly place to go, for example.
I don't think there is anything particularly wrong with an inexperienced person shooting a wedding, as long as the bride and groom have low expectations, which can hopefully be bettered. Maybe for a very low budget wedding. On the other hand, if the wedding is costing 20k+ and they're just trying to skimp on the photos, they might regret it.
