Is there an icon set containing icons for different platforms/stores (e.g. App Store, Play, Windows 8 Store, etc.)?
I am interested in grayscale icons similar to Glyphish and Glyphicons.

I can't find anything about Win 8, but for Google and Apple you have to use their logos.
For Android / Google:
We encourage you to use the Android and Google Play brands with your Android app promotional materials. You can use the icons and other assets on this page provided that you follow the guidelines described below. You may use the Google Play Store icon, but you may not modify it.
As mentioned above, when referring to the Google Play Store app in copy, use the full name: "Google Play Store." However, when labeling the Google Play Store icon directly, it's OK to use "Play Store" alone to accurately reflect the icon label as it appears on a device.
And the same applies to Apple:
An App Store badge must be used in both marketing and advertising communications, such as TV spots, print ads, video trailers, email, newsletters, and websites, whenever you promote your app offered on the App Store. Only the badges shown here are approved by Apple. Badges must be used as provided and cannot be modified.
Only a partial answer, and not grayscale - but I found this Google Play icon pack which you may find helpful.
If you're looking for a free and decently customizeable solution I would recommend Metro Studio.
While you do have to download software, it does allow you to customize icon size, colors, and backgrounds (you can remove background too and import the icons to Photoshop, or easily trace them and customize them in Illustrator).
I recently used this on a web project and I was very happy with the outcome.
I find this one useful and fully sufficient on many occasions. You get both PNG and PSD, so it's easier to customize them.
