Here are the answers I know off the top of my head:

-What is a botnet and how do I create one?
A botnet is just a large group of agents, usually running individually on a bunch of pre-hacked nodes, with a botnet program to coordinate them. You can subscribe to the whole botnet with a single subscription, but every interaction has to go through the botnet software. You can use botnets for lots of stuff - mostly when you have to perform a relatively simple task on a lot of different nodes. Really large-scale hacks tend to use botnets.

-How difficult is it to hack cyberware and what exactly can you make it do once you hack it?
As difficult as the GM makes it, really - it's pretty circumstantial. In general, externally visible cyberware uses hardwired connections rather than wireless, meaning you'd have to physically jack into the 'ware to hack it. Smart users will also disable any wireless connections that aren't absolutely vital. In either case, you're probably going to have to either get the user's AID and spoof every one of your commands to the 'ware (at the admin level) or hack on the fly for admin access. If your victim is smart he'll probably have all his 'ware slaved to a commlink with decent stats and maybe some IC. Again, it's as hard as the GM wants it to be. Unwired has a section that covers this in pretty good detail, including a list of hacked cyberware examples. There isn't really an exhaustive list of possibilities anywhere, though.

-How are Nanites acquired and deployed?
Acquired like any other gear, deployed according to each nanite type's Vector entry. Cyberspurs, darts, capsule rounds, squirtguns, gas grenades and so on can all be used to deliver a nanite payload, depending on the vector.
