Front

As a rule of thumb when programing, I always have the front arrow facing towards the audience, be it hung or sitting on the ground. For fixtures that don't have an arrow, I just make sure all the fixtures face the same way.

Basically, if you program a scene with the lights facing 'Front', be it hung or sitting on the ground, they should always face that same way. The only things you might have to tweak are tilt positions then.

I have programed whole trusses on the ground before, then tweaked once the fixtures were hung in the air. It works if you are dealing with a lot of fixtures and don't have the space/time to setup the full rig and hang everything. Also makes trouble shooting easier with everything on the ground to where you can easily get to it.

Let me know if this answers your question.

I am only using 2 of the accu spot 250 ll

But when I program a scene it projects to the rear of the "Front". So does everyone have to go to setting, xy and move the lights out toward the Front. Seems strange,am I doing something wrong????

Nope, nothing is wrong. It is just how you are programing. I am not sure of the home position on Accu Spot 250s, so it might be that when panning around, it goes to the 'rear' first. It is not a big deal, just swing them around. Remember front and rear are relative. The front is what you make it, likewise with the rear. Just be constant in your setup so as you add more, everything works the same way and you don't get confused.

A trick that big consoles use is they set the home position to be 50%, 33%, or 25% for pan (fixture dependent since some have greater pan ranges then others) and 50% tilt so the fixture is straight up and down and looks all pretty when not doing anything. Also helps keep you out of the limits and concepts of front and rear are easier to think about. If you ever go to a large concert, when movers aren't downing anything, you will see them generally straight up and down like described instead of at the extreme pan and tilt limit.
