Eminence Sigma Pro-18A-2 18" Cast Frame Driver
I am using these as subwoofers and was wandering where to cross them over. The highs are placed on a pole above them.
This depends on how low the main speakers can play safely at the volume level you need. Generally subwoofers are crossed between 80-120 Hz, so you will have to dial them into the best sound to your ear.

I have 2 of the EV ELX118 subs and I am thinking of replacing them with high output drivers (above 500 RMS!). I am wondering if the the Sigma Pro-18A-2 18", would be ideal replacement? other alternatives? Please help. Thanks
The Sigma is an incredible driver for the price and will work very well in that EV cab, although I cannot say what specific differences you will here.

Would these be a good upgrade to Peavey PV118 cabs? If so, would a QSC PLX2402 bridged providing 2400W into 4 ohms (two of these in parallel) be a good idea?
These will work very well as replacements for those cabinets. 2400 watts will certainly be overkill for a pair but there is nothing wrong with having the headroom. Keep an eye on woofer excursion and I would recommend a HPF set at 35-40 Hz.

Would these drivers be a good replacement for EV Eliminator Subs? Also, the EVs were 400 watts. If I'm using the same amount of watts(2400@4ohms mono split to 2 subs), what kind of audible differences would the 650 watts of the Sigma Pro-18A-2 provide?
Yes these will work well in those cabinets. The additional power will barely be beneficial in the long run and might gain you an additional 1-2 dB in overall output at higher volume levels.

I have a couple sigma pro 18a 2 speakers but need to know the specs to build my speaker box
I would recommend a box with external dimensions of 22"H x 28"W x 18"D using 3/4" material. A single 6" diameter port that is 9" long will tune the box to 34 Hz.
