Welcome sir! I used to be heavily involved in FAL's (hence the handle, right?) I then got into bolt guns, sold all my FAL's and went that route. Of all the guns of sold/traded, I miss my FAL's the most.
800 yards is more than plenty for a beginner to get going.
In terms of "novice," let's discuss your choice of optics. What are you trying to do? I know your scope has a lot of magnification, and that appeals to many folks, but is that what you really need? It is more of an "F Class" type scope (obviously doesn't mean you can't shoot with it just fine). I think you'd probably best be suited with their 5-25 or 3-12. Those may be better suited for your needs.
My piece of advice at this juncture is to dry fire a ton...more than what you think is sufficient, then multiply that by 3, is generally the standard.
What kind of trigger is in your FAL? If it is the factory trigger, you may want to consider upgrading it. I believe JARD makes a decent FAL trigger.
In terms of shooting longer distances, do you know your ammo? Do you know how to interpret ballistics info?
Keep us posted.
