MPs are responsible for the people who live in their riding (geographic area).
Since you live in the US, you don't have a Canadian MP (unless you live part of the year in Canada in which case you need to look up who is the MP responsible for the area where you live in Canada part-time).
If your partner is Canadian, then the MP from riding that s/he lives in (or if outside of Canada, the last one they lived in, especially if you intend to return) will likely be responsive to certain requests for assistance.
Not really much, from what I gather. It seems the most helpful they can be is getting updates on your case faster than you yourself can. They cannot expedite the process or affect the outcome of applications.

Actually, I'm not sure it was entirely a coincidence, we called my husband's MP after waiting 4 months for SA on a US outland application. The MP called them 3 times over the next 2 days and the day after that we were finally issued SA. So I think it depends on how persistent ( subtext annoying possibly) your MP is. Because my application went basically from them having nothing on me to having my whole file. It even states on my eCAS that the application was received March 11 and SA was July 17th.
