After checking into my hotel room I had reservations at the Borghese Gallery at 5pm. Since I didn't know the bus system and knew it was out of the way I took a taxi to the gallery which was about 15 euro one way. I really only needed 45 minutes for the entire gallery as there wasn't very many people. Its not labled well but when you go in the reserved tickets are to the right. Then you can turn to the right again and get an audio guide which I didn't do since I had my handy Rick Steves Rome book. Plus from what I heard most were not working well. You also have to check in your bags at the bagage counter and the person will give you a key with a matching number. Don't loose it. The gift shop is nice but pricy and small. They do have a snack bar but it was closed by the time I got done with the museum walk. They have very clean restrooms so I suggest using them before walking around the park down to the Spanish steps.
