Re: removing front seats
see the below link for more info, I managed to do it so it can't be that hard, recommend if your doing it one your own cover over the door sill as you'll probably want to rest it there before carrying it further.
cleaning worked a treat, and you can get the replacement trim bits of plastic for not much money from either the dealers or vagparts, can probably post all the part numbers if you need them.
suggest doing it when warm as ess_three said as it's a *****.
