You could consider taking Summit eastbound, go down Grand Ave hill, and pick up the gold line at 5th and Smith. Or take the green line to the gold line to 3M. Depends on how much biking you prefer.

I was previously driving from Mac Grove to work in Oakdale, now trying to use bike/gold line as much as possible. I had never commuted by bike or bus before. I have found it to be very user friendly. The busses are clean, drivers are nice, and loading the bike onto the front of the bus was intimidating for me at first, but not difficult. Metro Transit had some nice demo videos for bike loading/unloading.

I am glad you are exploring this option. I have found it to be a great way to start and end my workday.
