Close, but even better. Thinner front to back, nicely rolled edges. You'll like it.
2) is the lighter weight wood going to be lacking in low end?
Nope.
3) is it quiet? Last year I ordered the complete prewired harness with pots and board and had it profesionally installed on my L-2500 and it still buzzes if I take it out of passive or flip the series / parallel switch
Like any bass with Jazz-style pickups (properly wired, of course) it will be hum canceling when both pickups are at equal levels.
As to the L-2500: If wired properly and in good electrical condition, it should be virtually silent. Please differentiate between buzz and hum.
If you're hearing hum (roughly a B on the A string or 60Hz here in the US), you should look for an open ground. At your bass' age, it could be the
bridge ground or a
failing jack. Both are common, the bridge ground on most basses and the jack on L Series basses.
If you're hearing buzz, then you'll want to check the jack and the pickups. If an L Series pickup has a failing or failed coil it will no longer be humbucking and will pick up single coil noise from the environment. To check the pickups, do a tap test. Passive, parallel mode, master volume reduced at the amp. Tap a pole piece on each coil with a small steel screwdriver. You should hear a clear and sharp sound from each coil and the sound from each coil should be pretty much equal in loudness. A softer and kind of distant sound would be the tap being picked up by the adjacent coil and is an indication that the coil being tapped is open or damaged. Flip to series mode and you'll likely kill the whole pickup.
A little more on buzz. If the pickups test good and the jack is in good condition, then you get to check your environment. Sometimes a REALLY noisy environment can put out so much noise that it overpowers the pickups. I ran into this here with my L-2500, where I had to re-wire and carefully ground a heavy brass table lamp. Problem solved. Also be sure to check earth ground feeding your amp as well as chassis ground between the amp and bass.
That oughta get you started.
