"Stellar- when you create a warp point opening into an anothers(ally or enemy) system..can they see the new warp point?"

Yes. It creates a warp point on both ends, and anyone can use it. The new WP functions identically to any standard WP.

"system wide nebulas-Is there planets to be found hidden in the systems that contain system wide nebulas?"

Not in stock SE4. You could mod such things in if you want to though.

"Crystaline torps- I had assumed because it was a "torp"...that PDG's couldn't target them...can they or can't they?"

They are a seeking weapon, so PDC can target them. Do not go off of names, but rather the Weapon Type. PDC can target any "Seeker", but not "Direct Fire". "Seekers" create an object that must travel to its target. "Direct Fire" just fire a "beam" that hits instantly (or misses instantly).

"..Crystal armour...does crystal armour regenerate X amount of points to the shields when the ship is hit...or when the armour is hit?"

It does it when the armor is hit. The shields must be down before CA can generate any shield points from damage.

" & Lastly...Medium storms that say opaque to most scanners...any idea what level scans they prevent...or if you have a ship in there is it as visible as if it was cruising right thru the system?"

Generally, storms (sector-sized) provide level 2 cloaking. Color does not matter for sector-storms. You can find the abilities possible on them in StellarAbilityTypes.txt. System-wide storms (nebulae) also provide level 2 cloaking, save the red one, which provides level 4 (undetectable) cloaking. Their abilities can be found in SystemTypes.txt.
