There are many and are used for attachment to surfaces. Pili are virulence factors. The DNA is single circular, double stranded without proteins. Ribosomes - 30S and 50S to form a 70S complex. Plasmids - Extrachromosomal loops of DNA, some code for drug resistance, toxins and other factors.
Spores can be dormant for many years.
They can survive extreme heat, desiccation, radiation and toxic chemicals. However, when conditions become favorable they revert to a vegetative state. Spore germination is activated by heat in the presence of moistures but the endospore must degrade the layers around the spore.
