Hi Jerry
As long as you have openings in your fuse for air to pass through, you should be OK. It's a good idea to pick up an infrared thermometer if you have any questions. But, if you can hold your hand on the battery or motor for 20 seconds without branding yourself after a flight you are pretty much OK.

I've found my motors, ESC and battery packs are about 10 degrees F over ambient after a flight, putting them in the low 100 degrees F.

An electrical spark is quite normal when you plug in these high powered battery packs to the ESC. (These ESC's have large capacitors across their input circuit. The spark results from the near instantaneous very high current charging of these capacitors when plugging in.) Keep an eye on the connectors through. After a season or two of flying, these connectors can have eroded contacts. When that happens, its a good idea to replace them.

As for the battery location, they were split into two packs to balance the model. The first pack is just forward of the wing tube, the second is just behind the same wing tube. With your two pairs of 4S2P packs, its a matter of making the model balance properly.

That model will really be powered up, so don't pull full up elevator at full speed. Don't know just how strong that model is, but would hate to make a fuselage shaped splat in the ground while your wings go bye bye!
