I can't offer help as to the drawbacks of cutting the tank open, cleaning it 
and welding it closed again.  You may want to check with a shop that cleans 
fuel tanks and radiators for advice.  Unless the punctures are excessive, I 
would say that repairing them and then doing an internal cleaning of the tank 
with ball bearings or pebbles is probably easier than cutting it open.  If 
you must replace the punctured side of the tank, you may have to cut it open.

As far as sealing the tank, I think you should do that.  Using the car as a 
daily driver keeps water from collecting in the tank.  I would say that there 
probably aren't very many TDs being used daily.  If you don't seal it, water 
will collect and rust will return.

Check out for the proper product for sealing a gas tank.  
Eastwood is a fabulous resource for auto restoration products.  A less 
expensive alternative can probably be purchased from J. C.  Whitney.
