Help with wii console ten points best answer!?

How do you make friends on the wii lol, i dont want to start playing games with strangers im just wondering. Also, on mii parade on the mii channel, how come there are never any miis there? do i have to make friends with other wii users before their miis will show up on mii parade. And last but not least, i seen a game the other day: House of the dead overkill which looked good, but do i need to buy a wii gun first or can it be played with just the remote and nunchuck? oh and one last thing, is it worth me purchasing a wii clic controller? what games work with this controller because i only got the wii yesterday and only have one game so far (super mario galaxy) would this game work with the clic controller? thanks in advance!
