I think I have found the problem. By default the entire TCA is not loaded in the frontend:
"Normally in the frontend only a part of the global $TCA array is loaded, for instance the "ctrl" part. Thus it doesn't take 
up too much memory."
see: http://typo3.org/fileadmin/typo3api-3.8.0/d2/df2/classtslib__fe.html

So I've added the line
tslib_fe::includeTCA();
to main in class.tx_ttproducts_pi1.php

Now my additional fields are included in the front end!
Cheers,
Simon

PS. on line 145 of class.tx_ttproducts_pricecalc_div.php there is a typo:
foreach ($countedItems[$pricefor1Index] as $ $k4 => $v4) {
should be:
foreach ($countedItems[$pricefor1Index] as $k4 => $v4) {
