Automator: "Ask for Text" pass to "Rename Finder Items" possible?
Heres a script to rename the file to the correct format. But you must move files out of the folder after being processed or it will prompt to change the file name again, as you will see with this script.  Please edit your question to include where you would like to move it (or even a folder select).  I will also add the tag part after.

Use the "Run AppleScript" action for this:

on run {someFiles, parameters}
    set theMonth to (do shell script "date   +%m")
    set theYear to (do shell script "date  +%Y")
    tell application "Finder"
        repeat with theFile in someFiles
            display dialog "Enter Static Text for " &amp; the name of theFile default answer ""
            set theStatic to the text returned of the result
            set theEXT to (name extension of theFile)
            tell application "System Events" to set the name of file (POSIX path of theFile) to theStatic &amp; "_" &amp; theYear &amp; "-" &amp; theMonth &amp; "." &amp; theEXT
        end repeat
    end tell
    return input
end run
