Attn: Speaker DIY expert

I want to upgrade the crossover on my DIY monitor. It's a Jim Griffin design with Jordan JX92s and Aurum Cantus drivers. I put some no name brand crossover parts from Radioshack on it . Can somebody tell me what is the best capacitor, resistor and coil to buy. Please include the type and brand and the store where I can buy them.

Here is the list of parts that I need:

L1 = 1.5 mH 16 awg.
L2 = 0.3 mH 20 awg.
C1 = 6.8 uf
C2 = 5.1 uf
C3 = 15 uf
R1 = 8 ohms 10W
R2 = 3 ohms 10W
R3 = 1 ohm 10W
PCB board.

Thanks everyone, I appreciate taking your time.
