As you've got some StewMac straight edges, are those first several frets flat with the rest of the fingerboard? You might check them checking their heights with the long straight edge / short straight edge -few-frets-at-a-time comparison. I'd agree that a low-hours axe would probably not need re-crowning, but for a few frets to back out a hair would not be uncommon.
I generally use whatever strikes me when it's new string time: They all go dead PDQ and then they all sound alike !
I like bigger strings, so right now I'm running D'Ad XL-Fives, 50-135 (EXL160-5 set, to be exact).
My 'generic' setup is basically the same clearance over the first fret (nut height) and the last fret (bridge height) and a slight relief, generally along the lines of a little over a 16th on the B side and a little under a 16th on the G side both ends, and relief around .011 to .013. As long as I'm in that neighborhood, I'm good, and it will vary some with the season and whatever strings it's wearing.
And basses do vary. My red Spoiler refuses to budge with the weather, it never moves. The green one is much newer and I have to get hold of it once or twice a year (although it may be less than thrilled wearing a 50 G and a 70 D!). And the red one will play 'straighter' than the green one regardless of how much I tweak on it. If I had better technique, the red one might play with a dead straight fingerboard, which is very rare.
I often wonder what a Pain in the Ass it would be to play with these tweaks with a conventional bass, screwing around with neck bolts, a conventional nut, and separate bridge saddles. I could have never learned setup anywhere near as easily on an axe like that. The Alembic feature set makes learning this an utter breeze.
