First timer, and unfortunately, will miss most of day 1. However, on Sunday, have tickets for the grandstand. (Figure that is a good place to start for a first timer).
Not sure of the other days, but plan to hit Ballaugh Bridge/Sulby; I am staying in Ramsey, so plenty to catch there by the sounds of it, and for sure Creg-ny-baa as I've been informed it is a legendary TT tavern. However, open to any suggestions for viewing that are not the usual suspects of places to watch. Also, relying on public transportation or meeting new friends with cars. Ha.
