I'm interested in having this track produced and mixed well, because I like the idea.
I'd start with drums, because it's a complex instrument.
Don't ever use completely processed drum samples (toontrack/ssd) for your "groundwork", maybe when it comes to layering these libraries can be pretty good.
Once you finish with your drums - add bass, connect it with kick and, if possible, with snare drum.
And only then you go for guitars.
It's a mixing process, not a junk yard - first you go with complex instruments, then you add everything else.
For drums I'd use this free library:

It's a very good library in case you don't have AD or BFD.
Go with that and when you return - you'll have a far better mix than you have now.
