Wiring accessories for safety?

Hello all,

In my 64 chevelle, I have a stock fuse block and i am running the following accessories:

-Electric Fan w/ relay (fuse box IGN)
-Electric kickdown (fuse box IGN)
-Stereo (fuse box ACC)
-Electric choke (fuse box ACC)
-Amp (to BATT) with inline fuse

I do not want to overload the system or cause any shorts down the line, what would you guys suggest for safety, i was thinking an additional fuse block or just using inline fuses, or is my system ok as is?

also here is m schematics for the additional fuse box if added

thanks

tony
