[LS short box]

Those cams listed above are going to be pretty lumpy at idle. IMO if you choose one or the other I think a 3600 stall TC is in your future. I like and buy either Yank or Circle billet converters. Either can set them up to drive almost like a stock TC.
I would and maybe you already have included your tuner in your parts selection including the injectors and see what he thinks combo wise.
Just as a side note there are a couple of somewhat local tuners that I have used and have done a great job tuning my LS swaps. Both have told me the same thing in regards to engine HP. Some folks spend a $1000 to chase 10-15 HP.
