How much more do I "need" to buy.

[strm_trpr]

I am building up my equipment to start loading .45acp. I got a boost start on this by picking up a whole bunch of stuff from a friend who got out of reloading. So, As of right now i have
10,000 once fired but still dirty de-primed brass.
about 5,000 large pistol primers,
a rock chucker press,
an rcbs manual powder scale,
a lee powder measure,
a lee carbide 3 piece die set (brand new),
100 FMJ 230 grain 45,
a rcbs caliper/meter
a lyman reloading book.
and about 8 un opened cans of bullseye powder.

I think I still need
a tumbler with media
a trimmer (but what kind should i get)
a handheld primer (RCBS maybe)
a de-camfer tool
a trickler

what am I missing guys. I have a lot to learn still and am reading a bit every night but, I don't wanna waste money and wanna start developing a nice range load for my 1911.
