Longish hair for guys: how do i get these styles???????

Hi

I am currently growing my hair out (for like the 4th time in the last year or something). Anyways it`s been 4 months since i`ve seen the inside of a salon and aside from me hacking at my ends with a nail scissors, it hasnt been cut since the 10th of February.

My hair is currently just covering my ears at the sides and above collar length at the back with longish layers and bangs that are almost eyebrow length. (Kind of like Rob Thomas from Matchbox20 or the Beatles with layers and grown out about 2 months)

Anyway the style in question is the one worn by Kevin Richardson of Backstreet Boys on the videos for Shape of my heart and the call. It`s sort of mid ear length i think at the sides and longer at the back with lots of layering and some feathering i think.

I also like Eddie Cahill`s do - he played Tag Jones on Friends and had a role on Felicity. Which is very similar to Kevin`s but shorter.

I think these styles look way cool and would love my hair to look like that eventually.

My hair is slightly wavy and quite thick. Will the style suit me and also how can i get it???

Pics of Eddie`s hair can be seen at one of the urls below : not sure which
