The Nude is a great case for the money, but it's not the best case out on the market. To find the best case, it comes down to personal preference. I have a video review on my YouTube Channel on the Nude if you want to check it out. I also have a review of the Candyshell, which is another great iPad case, but not my favorite or the best in my opinion. Right now (and probably staying this way for awhile) I'm using a SGP Anti-Fingerprint screen shield, ZAGG back protection, and a sleeve (alternating between the Incase Slip & a Cocoon Innovations Sleeve).
To answer some of your questions, the screen shield from Switcheasy is probably good if it's the same as the iPhone Switcheasy screen shields. The Pure screen shield is a crystal anti-static screen shield which means no liquid installation. ZAGG screen shields are horrible, but I love the back because of the grip from the rubbery feeling. I'd honestly recommend a SGP Anti-Fingerprint screen shield. The stand is honestly not really worth anything. There are no viewing angles and it just feels cheap. Hope this helped you out a little bit in deciding.
