Hi,
1) DEC documentation which more fully describes all the instruction set (in
more detail than the PDP-8 handbook)
Not DEC documentation but a good resource:
http://homepage.cs.uiowa.edu/~jones/pdp8/man/
I've written an emulator purely from these pages and it passes the
MAINDEC-8E-D0AB-PB instruction tests.
Here is IAC described:

2) Some more instruction tests in assembler source code format. I have
found lots of binary files but I would prefer assembler source code format.
I am using a pal compatible cross assembler.
I don't have any of those. But I've used Krten's d8tape to dissasemble
BIN files with good result:

That and the source code listings on bitsavers.

Also I did not mention earlier my PDP-8 diagnostic page:
http://www.ak6dn.com/PDP-8/MAINDEC/
has more or less what you asked for. It has all the base PDP-8e series CPU core
diagnostics as listings
in PDF, binary tape images in BIN and RIM, and disassembled sources in PAL and
assembled LST.
BTW my PDP-8 implementation in Verilog (not VHDL) passes all these diagnostics,
as well as running
chess, focal, and other such images.
