Are these parts compatible?

[macbook pro i5]

CPU:i5 2500k
Hardrive:WD Caviar SE16 750 GB
GPU:Geforce GTX 550 1GB dedicated
MOBO:GA-H77M-D3H
Case:NZXT Apollo
PSU:HCG-750 750 watts
Cooling:Scythe Ultra Kaze 120nm 3000rpm
Wireless:Asus PCE-N10
RAM:Kingston HyperX DDR-3 1600MHZ

Now I would like anymore advice on what the best pricing I can get for these parts or if they will work with each other.

They'll work together. But if you want to get the PCI-e 3.0 out of those slots you will need an i5-3570k. With the 2500K they will only work as PCI-e 2.0 slots.

I don't mind it working as a PCI-e 2.0,because I don't have the cash for the newer ones,oh and this is 100% compatible right?
And sorry to bother you so much but what's the difference between PCI 2.0 and 3.0?

PCI-e 3.0 has double the bandwidth. Also you may want to check other stores. There is little to no price difference between the 3570k and the 2500k. Heck the best price I can find is the 3570k for $25 less than the 2500k.

Thanks! here in NZ I got the 3750k for $2 more then the 2500k which I am happy about ,And how would bandwidth help in this case?

Double the bandwidth

PCI 2.0 vs 3.0 isn't gonna make a huge difference unless you go with a 3.0 card. Basically 3.0 is future proofing yourself. IF you can get a mobo that supports it thats great. Then you can upgrade to a 3.0 card in the future. Currently i think only the AMD 7k series and the nVidia 600 series are 3.0 and while you may find a cheap AMD 7770 for $150 or less your GTX 550 may actually be better. Look at www.tomshardware.com for benchmarks or just search around. Just because something is brand new doesn't mean its always faster.
