Honestly, your list above looks alot more like an AP setup than EAA. Yes, it will work but I think you can do things alot more simply. If you intend to go into AP eventually then this setup makes alot of sense. But as was suggested above, you don't need to guide or the ASI Air and you will need a PC to run a capture program like SharpCap.
For EAA, I would rather have alot more aperture. The refractor will be great for AP but there is nothing like aperture to make the most of a quick exposure.
Finally, alot of of us do quite well with just an Alt-az mount (so no polar alignment) but your mount choice will definitely serve you well if you expand into AP. It all really depends on what your needs are now and will be in the future.
I personally like to keep things as simple as possible and I value being able get going quickly and break everything down quickly.
