Final Tank stocking planning advice!?

Here's what I have:
55g with live rock, CPR hob fuge teeming with pods/chaeto/chaluerpa, slim skim skimmer, 2xkoralia750's, and a AC 75 filter, gonna me mod'd to another fuge about 6 months old

48 Cree led system!

Livestock:
2 false clowns
bicolor dottyback
chromis
yellow tang
mandarin( iseeded the tank multiple times for months to prep for him, and continue to target feet and re-seed monthly)

Thinking I'm maxed on fish?
or could i do yellow prawn goby with pistol?

Thinking of adding a cleaner shrimp?

Corals
xenya, kenya tree(will be parting with shortly), assorted blah shrooms and zoas, then some 3 prettier zoa colonies, new red shroom, hammer, torch, frogspawn, huge ricordea and a baby, red blasto, 3 red acans, war coral, 2 red/green favia, 2 red monti's toadstool, GSP, small group of paly's and a candy cane my friend gave me that his led's bleached out!

So obviuosly, my bottom is getting pretty full and i'm full on green and red!

Gonna get a clam;
Saltwater Aquarium Inverts for Marine Reef Aquariums: Maxima Clam Ultra, Turquoise - Aquacultured
and thinking of this SPS starter kit:
Saltwater Aquarium Corals for Marine Reef Aquariums: Drs. Foster & Smith Certified Beginner SPS Frag 5 Pack - Aquacultured

Is there anything else for mid/high I'm missing that could add some color?
The sps and clam are gonna be in a month, gotta save up for a better test kit!

Also, what's the best site that sells cheap frags and clams? I kinda like getting the smaller frags and watching them grow! LA and the petplace seem to be the only places that have a good selection of both! I've used, LA, reefs2go.com, and saltcritters.com! LA is obviously the best, but saltcritters is cheap but no clams!

Thx for any advice!
