If you don't do high volume shooting then stick to what works. If you have money and just want to save time then only buy http://giraudtool.com/prod02.htm .
Also as far as trimming goes, just stay away from min and max lengths and you should be good to go. Especially with a factory chamber. Neck sizing is cool if you are shooting from the bench and want the most accuracy you can and not over working brass. If you shoot in dirt, rain, snow then bumping may be a better solution. I prefer FL bushing dies, but that is just me.
