1)
well since you call it with id=>$this->conf['PIDitemDisplay'] it will
link to the detail page of tt_products. You probably rather want the the
backPID here. Dont know how to get that but it shoukld at least be in
the HTTP_REFERER but looks like it is in tt _products=>$row['uid']
somewhere also.

2)
You have the problem that get_url uses $piVars[$this->prefixId.'[$key']]
which is correct for most modern extensions since they prepare/expect
there piVars in an array myext["var1"], myext["var2"]. But that is not
the case for tt_products! So you need to find the line in your code
which puts that "prefix" in there. Maybe you have to  call get_url not
with ...tt _products=>$row['uid'] but somehow with 'backPid' and
'tt_products'.

Be patient. Everything is there and prepared, it is just not put
together correctly yet.

So basicly you need to modify the name of the vars, values are all
there.

This is what I use, derived/copied from the mailarchive:

function get_url($tag = '', $vars = array(), $unsetVars=array(),
$usePiVars = true, $target = ''){
                //debug($target);
                if(!$target && $this->internal["target"]) {
                        $target = $this->internal["target"];
                        }
                $vars = (array)$vars;
                //debug ($vars);
                $unsetVars = (array)$unsetVars;
                //debug($unsetVars);
                if($usePiVars) {
                        $vars = array_merge($this->piVars, $vars);
//vars override pivars
                        while(list(,$key) = each($unsetVars)){ //
unsetvars override anything
                                unset($vars[$key]);
                        }
                }
                while(list($key,$val) = each($vars)) {
                        $piVars[$this->prefixId . '['. $key . ']'] =
$val;
                }
                if($tag) {
                                return
$this->cObj->getTypoLink($tag,$GLOBALS["TSFE"]->id,$piVars,$target);
                                }
                else {
                                return
$this->cObj->getTypoLink_URL($GLOBALS["TSFE"]->id,$piVars,$target);
                                }
                        }
        }

hth,

P.S.: Maybe put up your get_url function somewhere so we can have a look
at it, or are you calling ->getTypoLink straight away?
