Is there a way to mass-star items in Google Reader?

No, but the keyboard shortcuts of s (star) and j/k (next/previous) should make short work of it.
A keypress macro program (such as AutoHotKey) could make even shorter work of it.
You could mass star your items by using the API, downloading a list of items and starring them one-by-one in e.g. a Python script. If you exported the items you wanted starred as JSON you could use this script: https://gist.github.com/1342172 to star them (or the experimental web implementation), naming the file with the exported JSON entries starred-items.json.
There is no way to do it from within Google Reader that I know of.
