from looking at the error's i would have to guess that your not useing Velious Release Candidate 1 from PEQ. your item error can be fixed by following what is posted here
http://www.eqemulator.net/forums/showthread.php?t=18990 #4 is what you would need to. not needed to be done using RC1.
so you will need to install perl to do either of option A. or B.
for the missing opcodes can find fix here not really needed but if you don't want to see them as missing in world you can do this
