That's awesome. Just went to my first game earlier this month against Wolves. Sat in the Main Stand which had a decent view of both ends. It was relatively quiet where I sat minus a few moans, some snide comments (that I agreed with) towards the ref from a 5 year old girl who sat behind us (Dad must have taught her well), and when the cat ran onto the field. So if you are looking for loud you might want to take up Wiggytop's suggest of the Gwladys St End.
We ate in the city centre before the game so I cannot help you with food near the stadium. As for pubs, we hit up The Brick first. Good atmosphere and full of supporters. Also had the earlier game on TV which was nice. Then we hit up the Winslow Hotel because I felt like we had too. Place was packed. Was replaying some highlights of older games. Also checked out the Fan zone which does seem like it would be a good place to be if you had people with you who were younger or didn't drink (as Wiggytop mentioned they have various food, drink, and entertainment). If you get over to the area earlier than we did there are certainly more Everton pubs to check out near the stadium.
Are you there just for the day?
