$res= mysql_query($qr);
$i=0;
while($row = mysql_fetch_array($res))
{
$res_arr[$i]["res_date"] = $row["res_date"];

Answer 1

mySql has a Week function.
if you change your query to :-
SELECT `res_date`,`res_time`, WEEK(res_date) AS `res_week` FROM `reserve_tbl` WHERE `doc_id` = '".$doc_id."'";
You will be able to use the res_week field to track each record by week number and therefore show previous and next weeks
