Basic help for turntable newbie

I'm looking for some basic advice on a used turntable I recently purchased (Michell TecnoDec.)

-What would be a reasonable budget for a cartridge for this turntable, and are there certain cartridges that are good matches with specific tables, or is it simply a matter of personal taste and budget?

-Is it possible to install a cartridge and setup the table myself, or is professional service highly recommended or required. If possible for me to do it, what tools are needed/recommended and where can I buy them?

-Any other advice or recommendations for things I have not asked about are greatly appreciated!
