yes you can use these to clean all trim including the door rub strip,
for shine i am assuming you mean a wax which is use after a wash and give protection and some shine to the surface, a dedeicated polish will give more gloss or "shine", there are hundreds of options, on which you get members opinions on detailing dreams or any of the threads by Ahmed yaar, search for them on the forum no need to create a sport thread for it.
best you should get a quality wax which will give protection and shine, depends on your budget, at the low end safe waxes are turtle wax from approx 400-600rs, DC wax for more, and then meguiars starting from about 1600rs and so on it will keep climbing in price/shine/protection.
pure polish just for shine after which it is still must to wax include Meguiars ultimate polish, CG glaze etc start from around 1600rs and up
dont use cosmic/formula 1 they harm the paint finish
