Sorry to sound negative but the question you ask would fill a book.
Unfortunately the only way you can go is to decide how much you can afford and go for it. As an example the three lenses you mention could cost as little as £450 or as much as £7,917!!!!!! Do you see the problem?
But if it's any use I would suggest 35mm Summaron, 50mm Summicron and a 90mm Tele Elmar, look for good condition from the 60/70/80s and budget for around the £13/1,400 mark. Although if I was starting from scratch I would buy an MP with a standard new Summicron and save up for the rest.
