If you're willing to spend the money it can be a lot of fun and a lot easier to get around if you stay in Pasadena. The area gets pretty congested for that time around the parade an game. Being close takes some of the stress and frustration off of that.
For the parade, the "50 yard line" seat is 14 S Orange Grove. This is right at the beginning of the parade and where TV broadcasts from. The opening and closing shows will take place right in front of the grandstand. All the bands, floats, horses are at peek form at that point to look their best for the TV audience. Additionally that grandstand has a VIP component with complementary programs, coffee and doughnuts. A close second is being at 414-450 West Colorado. This right after the parade comes around a big turn so it is slowed down a bit and the large local LA TV broadcaster broadcasts from there.
For the Game my guess is only high row end zone seats will be available on Tuesday. If you just want to be there that is great but you may want something a little better. Sections 15-H through 22-L and 1H - 8L are seats with seat backs. The end zone sections are benches. It is nice to have the seat back and not be squeezed butt to butt on the bench. Also you don't want to be too low. Lettered Rows and rows 1-10 are too low. You wont be able to see the field well. There are also some decent organized tailgate parties.
I pretty knowledgeable about the parade, game and Pasadena. Feel free to DM me with any questions you may have.
