I would also highly recommend parking and taking the T. If you aren't staying in the greater metro area, take Piratecat's directions and then go from 90E to 128N and hop on 2E from there. The end of the red line (Alewife) is down this road and has a huge parking garage on it. The red line will give you access to Harvard Square, Davis Square (where I used to live, so I'm biased, but still a fun place--home of Your Move Games as well), as well as Park Street, where you can connect to the green line (and see the Back Bay), check out the Common, or start to walk along the Freedom Trail.
One of the things I love about Boston is the number of high quality restaurants to be had. Depending on budget and total amount of time spent there, I'm sure I (or any of the many Boston denziens here) could give recommendations. Either way, you can't go wrong getting dessert and espresso at Mike's in the North End.
