I've finally done it!! !!W00t!! I believe is order

Ok, so here's my system now:
Shuttle AK31 w/ 1.2 T-bird, 1024DDR2100, GF4Ti4200, Pioneer 16x SLOT DVD, Samsung 32xRW, Seagate 80GB 7200 Cuda IV.
TC-4, Innovatek GF4 and NB blocks, Maxi Jet 1200PH (295GPH), Large leaky copper bucket.
Temps are...Well, right now CPU: 29C, System: 22C, with a room of 18C. The CPU rises (when left idle) to around 34C, but generally goes no higher. Haven't gotten the chance to put it under some load yet, but I don't really think there'll be a big jump.
The good point(s): Cool!! Much better than 54 idle with air. QUIET!!! I have a real tough time hearing the Maxi Jet over the Panaflo L1A in my PSU.
The bad points: I think you can see it in some of the pics, but the Innovatek NB block REALLY doesn't fit between the TC4 and my vid card....I mean REALLY.
The 3/8" tygon that I smashed over the 1/2" barbed TC4 isn't so great. I think I'd see much better temps if I got some 1/2" tygon, and also some 3/8OD, 1/4ID tygon (using clearflex right now).
THE LEAKY COPPER BUCKET IS UNCOOL!! Maybe if it didn't leak QUIET so much, but it really leaks LOTS and LOTS of water. Also large, and doesn't work all that well. Has to go.
My ghetto T that you can also see in the pic is somewhat....ghetto.
Tap water with stuff floating around it it...look like copper specs or something. Not so good.
So I plan to:
Build a rad like Gerwin's. Passive, right mate?
Get distilled water
Get 1/2 & 1/4 tygon
Buy an unGhetto T
WC my PSU (like g33k)
And my questions (FINALLY, right?) are:
Is this pump powerfull enough? For 295GPH it's really facing lots of restriction. Also when I build a rad..
Where can I find a copper/plastic T that goes from 1/2" to two 1/4"?
Am I tubing this right. At the moment it goes Pump(in rad)->CPU->T->NB+GF4->two 1/4" lines dump back into the bucket. I'd planed to get another T and go back from 2 1/4" to 1/2".
MUCHO thanks to EVERYONE who's helped me out doing this, and thanks to everone so much for reading this...I really need the advice!!
OH! pics. [ignore the firearm/knives under the desk, will you?
