The shoulder pads should definitely be removed. It's not totally outdated to have shoulder pads in your jacket, but it's pretty damn close. Your jacket should be tailored so that its shoulders conform as close to the shape of your own shoulders as possible without restricting your movement.
In fact, the entire jacket should be as close a fit as possible without being restrictive. It should be tailored to taper inward from the armpits down to the about the bottom of your rib cage, maybe as low as the top of your hips. This will accentuate the V-taper look.
Yes, shoulder pads can accentuate this look, but if you do choose to keep the shoulder pads, they should be as small and discreet as possible. Basically, you shouldn't be able to tell that they're there. Unless you have very narrow shoulders though, this shouldn't be necessary. If you do have very narrow shoulders, I suggest more lateral raises, shoulder presses and wide-grip pullups rather than adding or keeping shoulder pads.
