I speak Russian at home, but I can't read or write. Should I take 860:101-102?

No. If you do, you might risk not getting credit for them from SAS. We have created a course, 860:207, for students who have some proficiency in speaking Russian but who have never formally studied it and who cannot read or write. The fastest and most accurate way to make sure you're taking the correct course for your level of knowledge is to take a placement test. More information on placement tests can be found here.
