Answer 1

I imagine something like this would work. Just append the extra field after you do your array joins.
I don't know what your user_id column is called, i just assumed user_id
$insert_query_prefix = "INSERT INTO $target_table (".join(",",$columns).",user_id)\nVALUES";
add the user_id value to the values argument
$query = "$insert_query_prefix (".join(",",quote_all_array($data)).",".$_SESSION['userid'].");";

Look for "ADD HERE"... just tack the column name in after you get them and also add the data to the end of your array once its built... should be simple as that.
foreach ($columns as &$column) {
$column = str_replace(".","",$column);
}
//ADD HERE
$columns[] = "userid";
$insert_query_prefix = "INSERT INTO $target_table (".join(",",$columns).")\nVALUES";
while (($data = fgetcsv($handle, $max_line_length, ",")) !== FALSE) {
while (count($data)<count($columns))
array_push($data, NULL);
//ADD HERE
$data[] = $_SESSION['userid']
$query = "$insert_query_prefix (".join(",",quote_all_array($data)).");";
mysql_query($query);
