Hello Want2Fly!!
Sounds like you are started on a great ride in aviation -- way to go!
If money is no object, then a bit of tailwheel exposure at this point would be good additional experience. You'll always have the training, after all. But, if you're like 98% of the pilots I know, I'd just concentrate on doing what you need to do to finish up your PPL, and then go into the tailwheel afterward.
It sounds like it would work fine either way, for you. You're smart to get it -- it does make you a better pilot, for sure, just like the other guys have mentioned already.
Have FUN!!!
