Basically this will be a political stunt with no significant effect to make the US President look good for a sound bite. It is possible that the Administration may even clear the target list with Putin in advance so they don't feel they have to worry about a Russian response, though Russia has played them for fools repeatedly before.
They most certainly will not. That information could end up leaked to Assad very easily. And while Assad can't actually do much about the US strikes, this sort of information could cost the US some aircraft. And even if it's just a aircraft, that's still not worth it. Consider that there really isn't much to gain by clearing the list with Russia.
EDIT: I'm not sure how accurate this is, but the source is a decent and well established defense blog. It's a map of Russian and US naval assets in the Eastern Mediterranean. Before you get surprised and impressed at the total number of Russian ships, please consider that the majority are supply and support ships, and BDKs some of which (possibly all of which) have detachments of Marines on board. Only a few of those are actual warships.

Out of what's listed here:
BDKs (large landing ships)
Novocherkassk, Minsk, Peresvet, Admiral Nevelskiy, Aleksandr Shabalin, Kaliningrad
ELINT Ship
Priazovye
Combat Ships
BPK (Anti-Submarine Destroyer) Admiral Panteleev, SKR (Frigate) Neustrashimiy
Support Ships
Ocean tug Fotiy Krylov, fuel ship Pechenga, naval workshop PM-138, rescue tug SB-921, fuel ship Lena.
So what's shown here actually includes a total of two warships, 6 landing ships, various support assets, and one ELINT ship. I know that enroute to Syria is the Moscow cruiser (Black Sea Fleet) but it's taking the long way, and it has with it a couple of other ships. However even if they add to rather then replace ships currently there, it still won't make for much of a fighting force. It does however make for a decent sized force to evacuate Russian civilians still in Syria. Which would explain the very large number of landing ships which also serve as transports, the small detachments of Marines (for security purposes) and the lack of bases, and poor state of the ships themselves, explains the need for considerable support vessels.
