Hello okc_smoker and Welcome to the Do It Yourself Web Site and to the Gas Appliances topic.
Answer to question #1
The stove top does need a regulator. Line pressure from the meter is twice that which is needed for any household gas appliance.
Therefore, any gas appliance needs it's own appliance regulator. Regardless of what anyone says or rumors, etc.
Buy any appliance regulator at any big box store. Such places only sell regulators for home use appliances anyway. Any natural gas regulator that supplies 3.5" water column gas pressure to an appliance is OKAY.
#2 question has to due with plumbing and piping. Not cover in this topic. Best to hire a pro plumber when dealing with a potentially hazardous material such as gas, IMO.
