What is the standard string gauge and tension I should be looking to put on the 4003s? Should I be aiming for low tension strings like La bella 760fx extra light tension. This is my first rick and I dont want to mess up the neck, I read that people try to use low tension strings. Thanks!!
The new-style 4003 truss rods that have been on the basses for quite a number of years now can take any reasonable flats. However, I prefer OEM flats tone, so I prefer the Optima RB set, which is the spiritual successor re-creation of the OEM Maxima flats of the '60's and '70's.

Welcome to the board and congrats on your new Ric. Factory string gauges are 45, 55, 75, 105 I just got my 4003 walnut 2 weeks ago. Installed Pyramid Gold chrome-nickel flats, #640 long scale, 40, 55, 75, 105. I'm happy with them. Do a search on here and google for information.
The Optimas are also similar gauges. Remember that tension is a function of mass of the string, not diameter. Because flats have less gaps in the windings than rounds, flats usually have more mass for the given diameter, which results in more tension. The Optimas and the Pyramids have more tension for the same given diameter as the factory rounds. Again, the 4003 truss rods can handle anything reasonable, and these gauges are very reasonable, but whatever set is used, rounds, flats or otherwise, if not the factory OEM set, the truss rods will need a tweak to adjust for the different tension.
I second the Optima RB recommendation. I add the Optima Chrome set too - hex core and slightly larger gauges. Great strings. Pyramid Gold too.

Whenever I put TI JF344 flats on a 4003/4003s I find that it gets a bottom end that can't be beat, plus the lack of tension on the neck creates a really fun neck feel to play on. The challenge is to not get too busy.
I have optima rb,superlight chromes,labella LTFF and some Labella white copper tapes on various Ricks of mine. All are good. The TIs and pyramids represent more the extremes of tension compared to these. Ti’s tend to be a bit “limp” for my use, and pyramids exert quite a lot of tension on the neck,which isn’t always desirable. (Well, in my case it’s never desirable!) the ti’s do sound great,so hopefully you can get them set up for your playability preference.
Hint on the TI JFs: set the action a bit higher than you think it should be and the lower tension will make the bass feel great.
