Hi dope.
Wot Wellsy said... you have excellent gear and we all have our own agenda in this hobby.
Be confident that you've made the most important start.. you've purchased an excellent piece of kit.
I started on the cheap, and the quality of the equipment is a very important factor (my comparison here

Effectively, you've bought a
mini version of the 4" modular.
The 4" modular has your 2" pot as the base kit, with 2x 2"-to-4" reducers and a parrot and connectors.
Allowing you to further drop in a 4" reflux condenser and an appropriate number of 4" bubblers or sights in between the 2"-to-4" reducers to compile a versatile setup.
It really is modular!
From my research, the main advantage of a larger diameter column is that it can hold and process a larger volume of vapour.
A 4" column will process the same volume of wash quicker than a 3" or 2" equivalent, which translates to less time for the run.
But time aside, you can get the same quality regardless of column diameter.
enjoy the journey.
cheers
