There is a lot to do here.
For museums, if I were a tourist, I would check out
ICA Boston
http://www.icaboston.org/Museum of Fine Arts
http://www.mfa.org/(there is a Japanese tattoo print exhibit right now that is incredible)
Isabella Stewart Gardener Museum
http://www.gardnermuseum.org/(this is about a block from the MFA, and is a great museum. Also the spot where there was a huge art heist years ago, the pieces they stole still have placeholders on the walls)
For shows/live music, there are a lot of options based on what kind of music you like. General list would be the Middle East in Cambridge, TT the Bear's in Cambridge, Great Scott in Allston, O'Brien's in Allston, House of Blues if you like bigger bands, and there are a lot more.
For galleries, there are a lot of places but for me personally I don't care for a lot of it. If you like Juxtapoz type stuff, you might be out of luck.
Bodega is a good stop just to see how impressive the store is, and they have a gallery on Brookline Ave that showcases some good stuff. They make posts on Facebook about upcoming exhibits.
This is a short list and is by no means inclusive of all of the stuff you can do here.
I can try and help with restaurants too if you need that.
Let me know if you need any help with planning or have any questions.
