Very confusing indeed. If you're looking to join FW then I'm guessing you want PvP skills. For now I recommend training up the fun skills. People will tell you to train your 'core' but as a newbie I got bored shitless training them.

So get skills like: Preferred Racial Frigate IV/V (get it to V)
Most of FW combat is frigates, so this will be very important.

There are also a few weapon systems in EVE but once you choose the frigates you want, the weapon system should follow based on the ship hull bonuses. Get the weapon to about V (IV is enough to start off with), get related support skills to III/IV (if you need to know what the support skills are ask in help channels, something like: "what are the support skills for small hybrid turrets?" and I'm sure people should help out.

REALLY Important core skills that you must get eventually are:
CPU Management V
Power Grid Management V
Weapon Upgrades IV/V
Advanced Weapon Upgrades III/IV (requires Weapon Upgrades V)

Also for tank, you will want:

For armour:
Hull Upgrades V
Repair Systems III/IV

For shields:
Shield Operation V
Shield Management IV
Tactical Shield Manipulation III/IV (DO NOT TRAIN TO V, IT IS USELESS)

And finally a list of boring skills to throw into the mix that are too important to ignore, but not important enough to bother unless you're really patient and long-term oriented, unlike me:

Navigation V
Spaceship Command V
Evasive Maneuvering IV/V
Acceleration Control IV/V
Fuel Conservation IV/V
High Speed Maneuvering III/IV
Afterburner III/IV
Propulsion Jamming III
Thermodynamics III(Fun for hardcore PvPers once you get the hang of it)
Capacitor Management III/IV
Capacitor Systems Operation III/IV
Target Management IV
Signature Analysis III
Long Range Targeting III

May have missed some things but that's a good start at least until you get into EVEMon and start to develop your own skill plan. It took me 2-3 months to settle down and stop changing the plan though, so expect lots of jumping around depending on what you feel like. Don't fight it and force yourself to train super long skills. I made myself get a Cruiser skill to V in my second month, and that whole month was spent bored to death. Enjoy the early days!
