For the Strat, go with a Crawler. It's an awesome pickup that's nice and beefy. Thick, rich and dark, it will be perfect in that guitar and it has the best splits of any humbucker I've ever used.
I assume the Charvel will be used for more of a Metal application so depending on your exact style I have three suggestions for you:
Holydiver bridge/Emerald neck - Classic 80s Metal tone but also very versatile. Suits that type of guitar very well. The bridge is thick, smooth and very articulate.
Miracle Man bridge/Cold Sweat neck - Like the Holydiver, the Miracle Man is thick, smooth and very articulate. It has more bottom end than the Holydiver thanks to all the low mids and it also has enough highs for some fantastic solos. The Cold Sweat is a shredders dream and a very popular option here. Not as versatile as the Holydiver.
Alnico Warpig set - Again, a pickup that is thick, smooth and articulate but has even more crushing bass on tap. A very hot pickup with loads of bottom end but also apparently quite versatile.
