Is this the procedure I'd use to install these files:
Now that you've downloaded your favorite stock apps, It's time to flash them onto your device. For flashing apk's you'll need a Root Explorer or any other equivalent explorer.
Step 1: Download the Apk from the above links.
Step 2: Using Root Explorer, Move the downloaded apk to System/App folder.
Step 3: Change Permissions by tapping and holding the app. Make sure to set permissions to rw-r--r-- (0644)
Step 4: Reboot into Recovery.
Step 5: Wipe Cache partition and Dalvik Cache. (Advanced > Dalvik cache)
Step 6: Reboot your phone and you'll find the app(s) automatically installed in your app tray.
Enjoy your favorite stock apps.
Will wiping Cache and Dalvik mess up my Google Wallet install? Should I reset it before doing this? I'm really lost!
