LG enV VX-9900

I am sure this has been discussed over and over again, but I have a mac (with itunes) and I am debating on buying this phone. How can I transfer music from my computer to my phone? Do I have to buy a memory card or a music kit?

AND.. is this phone really that good - would you recommend it over the 8600 or any other of the new phones coming out???

Thanks!!
