Backup Camera & New Lens

I have a wedding coming up in September where I'll be the main photographer, and knew that it was in my best interest in getting another Canon body to use in conjunction with my other 5D Mark II and assorted lenses. My original thought was that I'd be able to use my Casio EX-F1 dSLR as a backup, but I wouldn't be able to take advantage of any of my Canon lenses. It is a bit of insurance to know that if something were to go wrong with one of my Canon bodies, I'd have a back up and be able to continue and not miss the action. I took advantage of a special rebate that B&H offered where you could get $500 back if you purchased a Canon 50D along with a Canon PIXMA printer. I have had use for professional grade prints in the past, and the PIXMA printer was only $795 regularly. I needed another camera body, and now I have a printer that only cost $250 after rebate. Score! This is just in time for a road trip to South Carolina, and I'll be able to play with the new camera on the way. Additionally, I added another "L" series lens to my collection with the Canon 16-35 f/2.8L EF Lens. Although it's pictured on the 50D below, this will really shine on a full framed camera for ultra-wide images. I'm fairly confident that I'll use the 16-35mm on the 5D Mark II during weddings, and the 70-200mm on the 50D for a little extra reach. I have 2 more items on my wish list before the next wedding in September, a grip for the 5DMKII, and a remote shutter cable to use with my pocket wizards.
