should I buy macbook pro (non Retina) or macbook air?

If storage is a must, I would go with the MacBook Pro and upgrade the hard drive after purchase. You can do better than the prices Apple charges for HD upgrades.

If you can find a way to live off of external storage, then a MacBook Air would work great depending on your needs. That is the question only you can answer:

External storage or internal storage?

Storage is a must for me my old macbook pro (June 2012) 9.2 has issues and so now it time for a new macbook but what to get? I need at least 1TB of HD my macbook pro had two hard drives (I replaced the optical drive).

If you need 1TB, the MacBook Pro (classic) is it. Buy the cheapest, replace the drive with a 1.5TB 9.5 mm drive, throw out the optical drive and replace it either with a small SSD drive to create your own Fusion drive, or another big hard drive.

What do you mean? Same way you install on the pro.
