Got myself my 1st 2nd hand electric guitar and rocksmith 2014 for xmas as well
Guitar: Dark Green Yamaha Pacifica 112J
Amp: Marshall MG15DFX amp
Tuner: Korg GA-1
Picks: Jim Dunlop Tortex Yellow Medium Picks 0.73mm.
I have read on a lot of sites saying that beginners should be using light pics, something like the Jim Dunlop Grey Nylon Standard Medium Picks 0.60mm or maybe even the Jim Dunlop White Nylon Standard Light Picks 0.46mm. The tortex yellow ones seem to be doing me fine though.
First thing I did xmas day was to replace the strings with some Ernie Ball Super Slinky, a lot easier than I thought...until I snapped the D string by overtightening the string whilst tuning it up lol. Had to wait a couple of days for my local music shop to open up after xmas to buy some new strings...wasn't best pleased to say the least. Once I got some new strings it was all good, have also adjusted the action and intonation as best I can. But will get my local music shop to do a proper setup for me at some point, just in case I've messed things up.
If you are going to change the strings yourself, make sure you pick yourself up a pegwinder. They are a godsend!
Loving Rocksmith 2014 so far, although it can get abit frustrating when you think your in the groove with a song and it suddenly throws up a new chord or technique that you haven't seen before. Certainly throws you off your flow at times that's for sure!
What I have found that helps, is the offically guide which explains all of the different symbols and techniques present in Rocksmith 2014. It can be found here:

There are 400+ custom songs available for Rocksmith 2014 on this site as well, but you have to register (free) to access them:
