Actually, spotter would not be a bad kit for a noob. You have the binocs to scout terrain and spot enemies before they spot you, and generally you are supposed to stay alive (ie. mostly out of contact). Plus you can be at the top with 0.1 kill ratio
What I played the most as a noob (back then, there was only NA) was actually engineer and anti-tank, and only took potshots at infantry without hunting them in particular. With mines, you can be out of the way when the tank comes, with AT kit you can snipe APC's and AT & AA guns (though going after a tank with stikkbomb or boombox is tempting, I did this regularly with 1:3 to 1:8 KDR but with a decent score). By manning AT guns you can learn a bit from the tanking without driving one, AA gunners are sometimes a dire necessity (El Al, Gazala, Alam Halfa) so learning that isn't all bad!
As for maps, I would replace Tunis with Chiara's Boobs (more tactical options than spawn-run-die) and the tactically difficult Supercharge (pubbies still tend to ignore the southern flags, four years into the mod) with Gazala.
