How to use jobs?
Firstly start by doing "/Jobs" to open the job menu. when you have done so a up should come up with several jobs. from this menu you can right click to chose what job you would like to join by right clicking the job or left click the job to get more info on the job. to begin with you can join up to 2 jobs and eventually you can have up to 6 jobs at a single time.
Recommended job for starters
a lot of people would recommend along with myself would recommend joining the hunter job since you can get thousands of $ per minute at certain spawners. when you are in hunter you can go to "/res tp kill" or whatever grinder you know of and kill mobs.

Can i use auto clickers at grinders to get initial money?
Yes you can but you have to be at your computer whilst your at grinders. this means you can not go afk whilst using auto clickers.
