Beretta 1301 Maintenance

So picked up an LTT 1301 from Langdon. I am new to shotguns in general. So, a couple general quetions I am hoping yall can help me with. For lubrication, I assume its not much different than an AR. Quality lube and hit all the standard areas on the bolt. Anywhere else? As for cleaning, I have watched the video that Ernest put out, but does this shotgun need to be broken down that far for every cleaning? Is there a rough round count for when this level of cleaning should be performed? My 1301 came with one choke tube from LTT. I assume this tube is what LTT sends out with this shotgun. How tight should the choke tube be? It was finger tight when I got the shotgun. I used the tool to reinstall it, but not sure how tight to crank down.
