The fuel rails already have a front, factory, crossover tube on them. Do I use a T fitting on, say, the feed rail? I have a weld on an fitting that I was planning to install on my tank for the return and again just use the 1/4 line on the fuel sender as a vent tube. Does the surge tank need to be vented as well?

the trunk would work fine. To fill the surge tank a simple internally regulated pump like the Holley red, Mallory, etc. would be fine, although most any pump with decent volume would work. You don't need a regulator for that pump, it just needs to be able to fill the keep the surge tank filled. It will have help from the main pump which bypasses back to the surge tank also. Anything beyond what the engine is pulling will flow back to the main tank through the top line from the surge tank to the main tank.
As far as a regulator for the main pump, I like the 13101 efi regulator from Aeromotive. I use their 11101 pump so this regulator will connect to the outlet of their pump with a #10 mail to male o-ring adaptor which makes a clean install. If you are using a Wal Bro or different pump that doesn't have a #10 outlet you'll need adaptor fittings to use this regulator. In that case a 13109 may work better for your application; handles good power and has smaller inlet/outlet.
A tee will work, I usually use a "y" as it flows more, probably not an issue on most installs. No vent for the surge tank, just a big enough line back from it to the main tank so there isn't pressure in it for the bypassed fuel from the main pump, which will screw with your fuel pressure at the engine. In other words, you don't want to restrict the bypassed fuel from the regulator as it will change your fuel pressure..
