Hi srv
With your 6mm GSO plossl, you are just over 200x. At that level, the seeing conditions probably start to blur out your image. On those rare nights of good seeing, you may be very pleased with the view. (By the way, are you waiting until Saturn has reached a good elevation and not looking through too much atmosphere?)
I wasn't very happy with my 6mm GSO plossl, solely from the eye relief which was so poor that I could not get in close enough to see the whole field of view. Apart from being better glass, I was happy when I got my Vixen LV 6mm - great eye relief and could see the entire field of view.
Yes, there are plenty of reasons to have a barlow available. One reason is that, with a barlowed eyepiece, the eye relief improves. That can make that 9mm plossl much easier to see through. 9mm + 2x barlow gives you 278x in your scope. Very useful magnification when the seeing is good
As Jeanette said, the GSO 2" 2x barlow comes with a 2"-->1.25" adapter for the smaller eyepieces. They seem to be reasonable workhorse barlows for an economical price.
Be ready with some counterweights for your scope (eg. speaker magnets) - the barlow plus the 26mm kellner will make it top heavy.
