Hi jrsmith23,here's my opinion on your trades:
Michael Redd for Manu Ginóbili
I think you did a great job,the latter is more promising.Menu is better at defense and his shooting is not bad.
Eric Strickland for Andrés Nocioni
It's hard to say.Nocioni has nothing very outstanding,while Eric Strickland is good at shooting and steal.But Nocioni is far younger,he's still in his rookie year,let him get some training and perhaps he'll be better.
Desmond Mason and Recce Gaines for Shane Battier and Jake Tsakalidis
I'd prefer use Shane Battier rather than Desmond Mason,Battier is much better at shooting and defense while Mason is only a dunker I think.But Jake Tsakalidis is not a good choice at all,he's so poor overall(40)and asks so much(2.9M)!!! You should get R.Humphery I think,he costs less.
Joe Smith for Chris Andersen
That makes me feel puzzled

.The only explanation in my opinion for this trade is that you wanna clear up some salary cap space,isnt it?
