your name is totaly down to personal choice so if your happy then cool, but if you're not linked to anyother team ie. the youth team for the pro team dyehard then I would maybe prefer a team name that stands on it's on two feet something tough like shockwave, aftershock, trauma, arsenal, rage or indiviual like nexus, dynasty, infamous etc etc
If you've got the chance and it's not quite right then spend the time choosing because it may be around for a while (Tigers since 1983!)
The best advice has already been given. Play, play some more, play again and then go down the pub and talk about playing. The ONLY way you'll get better is playing whether it's practice or tourny experience.
Personaly I much prefer the tigers playing against other teams - there's something that you can't drill for and that's the stress/confusion caused by playing someone else.
So get yourself down to the nearest tourny and kisk ass.
Also I love the comment about increasing your phone tarriff, very true.
