Which patterns and colours should be preferred for clothes while shooting in black and white?
About the colors - It doesn't really matter, it all depends on your color to black and white conversion.
I guess green or blue cloths will be easiest to manipulate (see below) because those colors have their own slider and they don't appear in skin tones.
About the patterns - I don't know.
Your camera's sensor only records color images, conversion to black and white is always a pot-processing action (even when it happens in camera), most image editors have lots and lots of options when converting to B&W and give you a lot of creative freedom.
Basically, as long as the colors in the image are distinct you can make them whatever you want in relation to each other.
For example, I downloaded this image from flicker (image by Nick Della Mora, license CC BY-NC, link to original image)
I loaded it into photoshop, added a channel mixer layer and moved the blue slider left (darker) and red slider right (brighter) to make the plane look white on a dark background:
Than I revered the sliders and now the plane is black on light background:
One way you might use clothing colours is to place emphasis on certain parts of the photo. For example if you were taking a portrait shot, a shirt of a slightly darker colour to their skin tone could help to pronounce the face.
I can't say much for patterns, I have always preferred a more plain look in portraits as I think otherwise they can provide a lot of distractions.
Excellent question. But I think you are taking the stick by the other side. First of all you need to know how to work with White Balance. The understanding of (informal called) "grey17" and how it works with light working is needed to archieve this, because you don't have to think in colours, instead tones. Red and blue are equal. Or not, if you change the light, or the white balance.
I suggest a book about working in analog with black and white.
I think that saturated would work best if you're willing to work with channels (blends, curves) and not just leave it to PS's tool. Why? if you're working with channels, saturated colors will maximize the difference between red, green, and blue, as well as maximizing contrast within each channel. This gives you much more freedom and ability to manipulate the image's contrast and tonal values. For portraits, faces are obviously important, and using the green channel is practically a must for faces.
