To avoid damage of any kind, it's best to remove your jewelry when showering, applying soaps or lotions, and during exercise or other activity that may cause physical impact to the piece. Things like soaps and lotions can build up in any crevices of your pieces and some chemicals have the potential to tarnish silver or damage soft gemstones. Any especially delicate pieces are noted in product descriptions and require great care to not be bent out of shape. Remember that metal may be hard but it's not indestructible.
Your gold pieces won't tarnish of course. If a piece does need a cleaning, a soft toothbrush can be used with warm water and dish soap.
If you're not wearing a piece for a while, storing it in an airtight container can help keep it from oxidizing. Can be cleaned with a polishing cloth if it tarnishes.
