1) Screen surface: Is it like using a mirror? Is it necessary to hold it in an angle so that it does not look like a mirror? Is mirrored indoor light annoying? Is it well possible to use it outdoors a) not in the sun or b) in the sun or is it not bright enough and / or mirroring the sun too much?
There should be no problem indoor. Outdoor in the beach you have to hold it in such a way sun is not in your face, but in normal situations (waiting for the train, etc) it's not a big deal. Raising the screen lightness also solves it in case of need. In 3 years with iDevices I've had no problems.

Which software is needed to transfer the, uh, files? iTunes? How does one get iTunes? Is it preinstalled? Does one need to get some Apple ID and sign some conditions to get it? Does it have access to all applications' files (I mean the texts, pictures, videos, sgfs)?
The iPad comes with the needed cable (and a wall mounted charger, since some computers can't give enough power for it to charge well). For a Windows PC, you need iTunes and an iTunes account (free, although to get one you need to give Apple a valid credit card OR a valid iTunes gift card, this latter case is used with minors, usually). Before having my iTouch and iPad I had an iPod using Windows and followed this route without any problems. I've also used the iPod Touch with Windows, also no problems. Of course to get an ID you say "yes" to something like 64 pages of legalese. If you are using Windows though, this should not be a problem, you are already liable for many, many things. Itunes has access to everything, but Apple (AFAIK) has access to just troubleshooting data, some location data related to application crashes and what applications you have downloaded, since this is tied with your Apple ID.

It can be used without a PC since iOS 5 (i.e. since a few months ago). You'll create your Apple ID and all other things using just the iPad.

There are almost no security breaches in an iPad or iOS device (unless you jailbreak, since then well, it's like running Linux without proper security in place...). Of course if you visit problematic sites, they can exploit an iPad (after all, jailbreaking is a security exploit), but then I see this more like a problem with the user and not the device, i.e. if you walk in a lonely, bad lighted street at night waving 50€ bills around, you're likely not going to get out of it. Apps can't do it: in addition to all the sandboxing (an app only has physical access to their data), they have the Apple Store checks (humans and machines check the code and program, they are quite thorough).
