am I missing any thing?

Do bass & drums need any kind of amp simulation?
In this picture, am I missing any other piece of hardware/software?

Thank you.

I'd probably go ahead and run my bass through your guitar set up just for the connection and you may want to put some compression on it on the way in. Drum wise, looks good to me.

So I don't need this thing between the triggers & mixer? http://www.zzounds.com/a--2676837/item--ROLTD3
