About the blue tack etc I would hold off on any other
suggestions about ways to improve your set up re
isolation until you see how the set up you have coming
works for you. Once you start tweaking you'll discover
that "everything changes everything" and once you have
a solid foundation mostly what you have to do is
"tune" your set up this is especially true of analog
playback, it is all about vibrations and resonance.

Adding mass to your desk wouldn't "hurt" but it may
change the sound in other ways that you don't like.
Adding blue tack may slow down draining of some
frequencies that you don't like or change thing in
other ways. Making your desk stiffer and lighter
would also change the resonant frequencies involved
but wrapping it in carbon fiber and drilling it out for
lightness may not be sound you like. With a vinyl rig
you have a lot of ways to tweak out the sound, mind
boggling really. It looks like the set up you're going
for is a good place to start tuning given the limitations
of being on a desk.

Instead of bubble wrap you can use a thick squares of foam and it will be better, but why your computer vibrates so much? Mine is dead quiet, why not working on that side in the first instance, in making the computer more quiet...
You can use under the TT also mouse pads, this kind of foam is really nice to absorb impacts and vibrations, and will be al ot thinner...

It makes as much sense to me as making car tires out of solid granite vs. MDF... neither works. I'd stick with the bubble wrap/inner tube/grip idea.

AFAIK, either by:

1. raising the mass significantly, thus lowering the resonant frequency. this the operating principle of high-mass TT designs.

or

2. adding additional "interfaces" which vibration has to pass through. a little vibration is lost every time a new layer is encountered. this is the design principle behind multilayer-type TT plinths or birch-ply speaker cabinets.
