1500 Dark Eldar, tips for certain armies?

So this is going to be my first army. I'll be facing Tyranids, mechanized IG (with vendettas), foot slogging IG, Tau, and possibly Grey Knights. I've given everyone upgrades using advice I've read on this forum, but was wondering if people could give me advice concerning how to use the list against the armies I mentioned.

Archon (Venom Blade, PGL, S Field) 120. Incubi x4 88. In Venom (Splinter Cannon) Total: 273

Kabalite Trueborn x4 (Blasters x4) 108. In Venom (Splinter Cannon) Total: 173

Kabalite Warriors x10 90. In Raider with Splinter Racks and N Shields. Total: 170

Another gunboat, same as above

Wyches x8 (Haywire grenades) 96. In Raider. Total: 156

Hellions x10 (Helliarch w/ Venom Blade) Total: 170

Reavers x6 (Heat lance x2) Total: 156

Ravager (N Shields) 115

Ravager (N Shields) 115

Army total: 1498

Now I know taking Hellions without the Baron is generally discouraged, but I love the models so I at least want to try them out before seeing what else I can spend the points on (Maybe a Razorwing/Voidraven). I think I'm planning on having them and the bikes in reserve, deep striking the hellions in to wreak havoc and having the bikes tear up men with their bladevanes and melt tanks. I think I have a fair balance of anti-infantry and anti-tank; gunboats to shoot up their men and the dual ravagers, wyches, bikes, and blasterborn to hunt their armor. Do you guys think I'm missing anything?

I think that's a pretty tight list, only thing I would worry about is how you'd deal with flyers, my 1500pt dual Razorwing list would give that a good going over! By all means, give those hellions a run-out or two.

Vendettas will be wasted against you.
You can stay out of fire arcs most of the time, and who cares if he pops a few transports.
