Wolffe, as this is over 24 hrs old and you sounded like you were reaching for the hacksaw, this may be too late.
I wouldn't saw them out if only for fear of the recieving threads. As a quick and dirty option, I'd use #8 rubber expandable plugs in the 'seats' (I'm assuming that these are SP 1419- "X", 3 peice threaded directional inlets). Not sure what the blue 'wrenches' are, but I've always had success with the SP 1419-T (it's a white plastic ~2x3", notched at the bottom to fit the notches in the seat, there's a hole at the top through which a screwdriver can be inserted to increase torque) if the screwdriver isn't enough, out come the 18" channel locks. If, by some chance, this doesn't work (unlikely) - I use the same channel locks directly on the threads (this wrecks the seat, but it does come out). Still having trouble - place a 2x4 against the seat and give it a couple good rapps with a hammer to break the seal (the plastic threads have bonded to each other on the pool side, so gently driving it back will loosen it).

What have we learned? 1) someone overtightened the 'eyeballs' 2) Overtightened 'eyeballs' can be a real pain to remove and are probably not going to be usable again next season. 3) Use the right tool for the job. 4) Post here before going to the pool store (I logged off 10 min before you posted), even if you're going to the pool store anyway. (Most times, it's easier and cheeper to use this site as a first resource, rather than as a last resource ) 5) POP

If you don't want it to happen next year, don't screw them in so hard, they work just as well when left a little loose (though if you have kids that like to play with them or a robotic cleaner that 'eats' them out of the wall, you do need to put them in tight). If you have reason to 'reef' them in, a wrap of teflon tape will keep them from bonding to the female threads.
I hope you resolve the problem and that you never have the same headache again!
