Exchange phone vs. drink holder?

Hi, I just bought myself a V70 D5 (diesel 163 HP Bj 09/02). The following problem. I hate these built-in car phones. My newer has the communication package. I would love to have a correct drink stop instead of the telephone keyboard. Can you change that? Also this pseudo phone in the center console bugs me… Also: Unfortunately I belong to the smoking guild and can hardly believe that there is no proper ashtray in the D5. Only such an emergency solution for the center console. Is there perhaps still any way to change that? Last question: Mine now has 255/50/17 tires. Is that good or bad. Does this make the car better/bader than with the serial tire? I am very grateful for a few answers!
