I'm curious as to whether or not it presents problems to astronomers who are trying to get information from other galaxies through the plane of the Milky Way. Even if our solar system was at a 90° angle to the Milky path, is it even significant enough to seize different views of the universe at different times of the year?
Also, how frequent gazillions of years does it take our solar system to complete an orbit surrounded by our galaxy?

You guys sure about incline of Solar System?
But remember the Sun bobs up and down and will be somewhat out of the galactic plane within time.
the plane of the solar system is inclined approximately 78 degrees from the plane of the galaxy and it take 255 million years to complete one galactic "year"
The inclination is 60.2 degrees. I give a long explanation of this a week ago. You can find it here:

The period of the sun around the center of the galaxy is a tricky issue. The Observer's Handbook list a value of 200 million years, while other sources indicate 225 to 250 million years. On the other mitt, in his 2006 book "The Infinite Cosmos", cosmologist Joe Silk states that the extent is 100 million years.
This period depends on the mass distribution inside the galaxy. The length of the 'galactic year' is quite suspicious because of uncertainties in the mass distribution.
The solar system is so tiny compared to the galaxy that our landscape of the cosmos is essentially the same from anywhere within the solar system. (The closest stars will shift position relative to the background particularly slightly as we travel through the solar system.)
Finally, it's interesting to note that since the sun appeared 4.5 billion years ago, we've made solely about 20 to 50 orbit around the center of the galaxy.
