does it not work with the settings for
METADATA
"RESULT_FIELDS" "col1, col2,..."
?
In principal XY layers should work as well with the auto-identify function.
In pm 3.1 you can set the debug level in the config.ini to 3 and you should get
the SQL command used for the query, written to the dir of the PHP error log and
with a name like pm_debug.log. This way you could check where errors could be.
XY layers are not so heavily tested by me since I don't use them very much.

you can use the function reloadMap(false) and execute it every 60 seconds. You
need a nested loop of a timeout command, like
function runPeriodically() {
window.setTimeout('runPeriodically()', 60000 );
reloadMap(false);
}
or something similar and run this with the body onload (or just put it in
pm_init()).
or have a look at the jQuery plugin at http://www.jasons-toolbox.com/JHeartbeat/
