What is your budget on every thing? Yes you can make your own spacers, and it depends if you have time or just want to get it over with and spend the money on the Ares.
I would suggest a firefly bucking and hop up, the stock hop up needs to be replaced now or you'll just have to do it later. Depending on your budget for a scope, I would suggest the Vism 2-10x50 or the 4-16x50 scope as they are rugged and don't cost all that much ($170-$190) then there are some Leupold replicas out there like the M3 3.5-10x50 for $80.
As for upgrades, look in the sticky's for more info on them as I don't know many other than the LRB mod and top dead center mod that you can do. New trigger is also needed.
