Launching App Store is explained in "QA1629: Launching the App Store from an iPhone application":

I'm not sure if it's possible to link directly to an update. I've found once an advice to replace "viewSoftware" to "viewSoftwareUpdate" on:

but since link for "phobos" is no longer used it might not work any more.
