Check your local laws and such, but chances are, you can just cut the stupic cat out all together. And as for the muffler, you might or might not be able to cut it out. (many states don't care at all)
The list of guys here, who have "straight piped" trucks, is very, very long.
As for going to a 4" exhaust, I noticed a difference on my truck. (and I've only got a downpipe back setup. The 4" exhaust just has more room, so a little less resistance. Plus, it helps lower the EGT's. But you don't "need" it by any means.
Don't burn your bridges, you might have to cross them again in life.
Don't sugar coat things. It covers up the taste of real life.
