So they Keyhole Cichlids... you still really want them?
I'm pretty sure they will be problematic.
The L155 is a nice looking fish (called a lyertail)
You could do a pair of phantoms 1 blue 1 green they look nice together.
My plecos like slate. They munch the drift wood in my tank but they hang out in the slate caves. Have you checked out the gold nugget? I would go gold nugget blue phantom green phantom then you could toss a bushy or 2 in there at some point if you like.
I would suggest waiting a couple months after you add the other fish to buy and add your plecos. I also always suggest using caution when ordering plecos on aquabid (I have only had bad experiences there) it's like e-bay in that your experience is only as good as your seller.
If you have a nice big LFS they can order stuff in for you.
I would buy everything but the plecos, let your wallet heal and your tank do it's thing. Plecos don't really need "company" so then add them one at a time. It's always fun to buy new fish so when you are ready for 1 buy it, then when you are ready for the next buy it.
Honestly unless you have decades of experience I wouldn't put anything really nice in your tank until it's been up for a while because chances are you are going to have some issues once you are set up.
If you go the bushy nose route I would get a bunch, get a black veil (long fin black bushy) a regular bushy, an albino veil, a starry night, a regular albino bushy etc mix it up, again I'd get about 1/2 of your stocking plan wait then buy another 1/4 wait then buy another 1/4 wait then buy plecos
