Hmm, I know it may not have been decided yet, so if it hasn't please say so, however . . .

What skill will be/is the "Recommended Skill" for explosives?

And Grenades?

Thanks

Various theories have been put forth, but until the rules are written, nothing can be said with any certainty.

Grenades are thrown weapons. Thrown weapon is (Strength + Dexterity) divided by 2, the result being rounded down. So if you have 3 strength and 2 dexterity, you have 2 thrown weapon skill.

Explosives skill is made up of two skills, Computer Operation and Perception. However, there is no equation an endskill, just for a percentage of setting up the bomb, which is (CompOps x 20) + (Perception x 5) = End percentage. So a CompOps skill of 2 and a Perception skill of 4 will give you a percentage of 60% of successfully setting up the bomb. 3 CompOps and 3 Perception however gives you a 75% however.

I don't get it.Admin Phryss said it's unknown and Cesodevo explained...

The second person repeats what is on the rules page right now, the first party points out that nothing is set in stone yet.

Phryss isn't an admin. But both are correct. The rules will almost certainly be modified repeatedly well before combat is released at all, so there is no real use in asking about this already.
