I am doing the same thing, I am going to replace my 235 45 17's this month. I am going with Sumitomo HTR Z II, everthing I have read and heard is good about them. Sumitomo and Dunlop are the same. The HTR Z II according to Tirerack.com are very good, and not to mention they are about 100 less per tire.
With regards to size, i am going with 235/45 fron and 255/40 in back.
