Replying to Film Camera

After being involved in the world of digital video for the longest time I want to start working with still images. I am looking at starting this whole process with a good ole vintage film camera. I was curious if anyone could give me a recommendation of camera, lenses and film to start with? I've been recommended a pentax k1000 and was wondering if that is a good option? Also I don't have the availability or option to be mobile enough to go to shop so are their do's and don'ts for buying camera online? I thank you all in advance for the help!
