Looks lik you already got the basics covered.
The SB-1000 has the 3-500ZG in it, but i normally don't run more as 500 watts P.E.P. on 160, and can reach Caanada/USA with ease with my inverted L, buut then it took me 2 years to get the 2100 feet of radials in/on the ground.... a never ending p0roject that...and most rewarding too.

Have fun with it ;)
