Yes, sorry..I should have said, I'm using the 580exII flash. Bouncing at 1/60 is way too slow. I'm using a Canon 50D. I wish I could make the camera go faster but keep f/4. I don't do manual because of the limitations there also when using the flash in ettl. Even when camera is in manual and you are shooting a bride the flash reads the white dress and cuts off prematurely. Men in black and it stays on too long washing them all out., Right now I'm shooting P and spot metering on face.
Sounds to me like you need to learn how ETTL works and how to use FEC (flash exposure compensation).

What you're describing here sounds like you used to work in Auto flash mode or are mistaking ETTL for auto. In auto, the camera triggers the flash and the flash stays on until it determines, through a sensor on the flash, that enough light has been given. However in ETTL the camera has the flash send out a "pre-flash" prior to the shutter opening. The meter in the camera then see's that pre-flash and does calculations as to what power the flash needs to fire at once the shutter opens. But, since it's the cameras meter, its going to try and expose everything as gray. Thats when you need to know how to use FEC
The great thing about the camera being in Manual and the flash being in ETTL is you set your aperture, ISO, and shutter speed to what YOU want them to be at (depending on the DOF, noise, and amount of ambient you want). Now with the flash in ETTL all you have to do is dial in + or - FEC depending on the scene. A lot of white? Dial in + FEC! A lot of black? Dial in - FEC
The problem with program mode is that it's going to try and expose for the scene without taking the flash into consideration. In low light conditions that usually means a max SS of 1/60. Like I said before, why fight against your camera when you already know what you want?
Set the SS to 1/100 (or 1/200 or 1/250 or what ever YOU want), ISO to 400, Aperture to f4. Cool, your camera is set and no more fighting with the camera over the SS. Now you're shooting the bribe with her brides maids, all of which are wearing light colored dresses. No biggie, dial in +1 2/3 FEC and boom great exposure! Next we have the groom and all his grooms men.....well damn there is a lot of black now. Well no biggie, I already have my SS, ISO, and aperture set so dial in -2 FEC and nice exposure it is!! (These FEC number are just examples. Different situations may need different values)
Trust me, you're doing yourself a major disservice by fighting with the camera in P mode. Not to mention in P the lowest you're going to go is 1/60 with a flash attached. There may be times when you want to drag the shutter to let more ambient in then use the flash to freeze your subjects
Learn Manual. Learn how ETTL and FEC work. Then just enjoy not having to fight with your camera any more
