If I use a password made up of ordinary characters (A-Z, a-z, 0-9) with
no specials then how many characters do I need to use to make AES 256
uncrackable by a brute force attack?

Well, to make your password not the weak point, you need 43
totally random characters.

Here's how that's figured:

AES256 uses a 256-bit key. There are, therefore, 2**256 possible
keys.

26+26+10=62

62**43 is approximately 2**256
