Hello, and welcome to the forum.

As the others have said, anything you do beyond simple cleaning to "improve" your new Luger will destroy it's collector value and financial value as well.

In answer to your specific questions:

Is it possible to get a more accurate date? Believe 1906

AS Ed and Don mentioned, this is a 1906 pattern Luger. I don't know of available production records from DWM that would nail down exactly when it was made. By 1918 they had reached serial numbers in the 82000 range.


What does the Eagle mean for the gun on the top? American/England import?

As mentioned, this model is an "American Eagle" model that was made for export to the USA.

What does the 17228 stand for on the barrel? 7.65 mm

As mentioned, it represents the barrel caliber. You are correct.


What does the B with the circle around it on the barrel stand for? Brazilian mark I think

I also go with Ed's explanation on this as a barrel for the Brazilian Lugers that went into American Eagle production instead. I was also thinking Boehler steel, but those are marked "Bo."...


What does the "3" directly in front of the trigger stand for?????

It does look like a worker mark, but it would be very unusual for them to be placed in a visible location. I don't have a better explanation.


What would I use and how would I safely clean/restore this piece of history? Will be doing as little as possible.

Well oiled "0000" steel wool on an oiled blued steel surface to remove active surface rust. Basically clean it with Hoppes No. 8, oil it properly and that's it.


Is there a way to find out or test if this is safe to shoot without harming myself or the gun? Will not be shooting this.

I personally would not shoot a historic and collectible firearm. The way to find out is to have it gone over by someone familiar with Lugers, and then load it and fire it. Be prepared for parts that might break, ending it's history as an all matching gun. Of course, there are those that must shoot everything they own. To each their own.
