for the first settings you show, i would darken the "specular colour" or lower the "specular value" with that setting being anything other than black you are gonna get a sheen to it, if you were to apply that to a skin texture as it were then you would get a wet skin effect.

For the second one, if you want to mat down the reflection effect, i would "uncheck" the "reflection lite mult", and either lower the "reflection value" or detatch the relection node altogether if you don't want any sheen, the reflection node is gonna be being affected by the lights in your scene a lot also, so if you have the default three infinate lights on then the clothes will be very shiny with those settings you have there. changing your lights to "spots" might help lower the glow effect, i'm guessing from those settings that they are supposed to be a bit latexy.
