Need an updated ARD login script for Mavericks

Question

We've been using the script below for some years now with very few issues (other than for some reason the multiple returns at the end were needed for some stubborn machines).
The script continues to work nicely in 10.9--assuming that the cursor is in the name field of the login screen.  More often than not, the cursor isn't.  Because I've yet to teach myself/learn AppleScript, I wander around the lab and manually click into the name field.
A:  Does anyone know how to tell the machines to place the cursor into the name field?
B:  Could maybe a future OS update restore the good old days where the cursor blinking in the name field was the default?
name="username";
password="userpassword";
osascript <<EOF
tell application "System Events"
    keystroke tab
    keystroke (ASCII character 8)
    keystroke tab
    keystroke (ASCII character 8)
    keystroke return
    delay 0.5
    keystroke tab
    keystroke "$name"
    keystroke tab
    delay 0.5
    keystroke "$password"
    delay 0.5
    keystroke return
    keystroke return
    keystroke return
    keystroke return
end tell

Answer 1

The less than signs did not have a space.  I took out the the first delay and the last return.
osascript <<EndOfMyScript
tell application "System Events"
keystroke “student”
keystroke tab
delay 0.5
keystroke “***”
delay 0.5
keystroke return
end tell
EndOfMyScript
got this error message
43:44: syntax error: Expected “given”, “in”, “of”, expression, “with”, “without”, other parameter name, etc. but found unknown token. (-2741)
Are you running your computers with an osx network user logon?  I am.
thanks.
