There are many ways they spread -- you can pass them via contact or droplets, and some can be airborne. Some are spread via vectors (ie mosquitos), and some are in water or food that are ingested. It really depends on what type of pathogenic bacteria you are speaking of.
No. Almost all bacteria are not. There are bacteria everywhere performing essential functions like breaking down dead animals and plants. Bacteria are essential to health helping digest food and preventing pathogenic bacteria from getting out of control.
No, not all pathogenic bacteria are gram-negative. Pathogenic bacteria can be either gram-negative or gram-positive, depending on their cell wall structure. Some common gram-negative pathogenic bacteria include Escherichia coli, Pseudomonas aeruginosa, and Neisseria meningitidis, while some gram-positive pathogenic bacteria include Staphylococcus aureus, Streptococcus pneumoniae, and Enterococcus faecalis.
The medical term for disease-causing bacteria is "pathogenic bacteria." These bacteria have the ability to cause infections and illness in the body.

Of course they do not. There are many other bacteria

yes
Firstly, pathogenic is not the opposite of anaerobic. The vast majority of bacteria are non-pathogenic, but this doesn't mean they are anaerobic.
"Pathogen" is something that gives rise to disease or infection. There are bacteria that do not do these things though, such as the culture in yogurt or the E.coli already residing in your stomach.
In Griffith's experiment, non-pathogenic bacteria were transformed into pathogenic bacteria by being exposed to heat-killed pathogenic bacteria, a process now known as transformation. This led to the discovery of genetic material transfer between bacteria.

Well they are both pathogenic
