First off, forget tab. NO reading gig will ever have it. So I'd learn to read standard notation even if you think you'll never need it. As far as chord charts or other shorter forms of notation, research the Nashville Number System. This breaks you of thinking of playing only in your favorite keys, and since transposing music to different keys is MUCH easier on a five (or six), it can come in real handy. It makes you think in intervals, and can really open up the fingerboard in the process.
While you do pick up the extra five low notes down to B, that's a bad reason to make that the only reason to buy a five, and sounds like you've realized the real reason is the more options for playing across the fingerboard instead of the more vertical shapes required on a four.
In the process, you are now on a bigger, wider neck, possibly a bigger and heavier instrument. Muting and some fingerings are very different. You may require more amp.
Fours and fives (and sixes) are similar but completely different animals.
I'd echo the advice to get a five and play it exclusively until you begin to get it under control, which can take a while, but like most motor and muscle memory, after a while it will come to you.
Good Luck,!
