Reply to Waves Plugins - Suggestions. Help.

Yo yo,
Looking to buy a group of plugins. 500 dollars. Im trying to buy a group of plugins which can be used on everything. Bass, Drums, Vocals, Mids, Highs. I produce heavy Dubstep. But always lead in with a melodic intro with some vocals.
Waves are the top of my list not only because of reviews and known quality but also because they are rocking for 50% off right now. Can't turn that down. Looking to purchase these today because the deal ends soon. Uh Oh.

Have these 3. Also need an EQ. ANY AND ALL SUGGESTIONS WELCOME. PLEASE.
Using Ableton Live.

Also produce with a friend so the Ilok helps me so i can use them if we make a tune on his computer.

Waves : TrueVerb
Waves : L2 Ultramaximizer. (Used as a limiter also)
Waves : API 2500 as my Compressor. Seems the most versatile as it can be used on busses and individuals.
