Whatever you may have seen, it wasn't 3 classes.

Your account still exists, if you remember you login and your password. All will be as you left it. No huge changes in Prophecies.

There has been alot of changes & updates since christmas in guild wars you would be better off using http://wiki.guildwars.com & http://gw.gamewikis.org for a full list of all changes etc.

1. There are some HUGE changes.
2. Your account is stored serverside so yes it will be fine.
3. You should be able to get a decent guild very easily, there are lots around.
4. There are 10 total professions in guild wars. You should have atleast 6* professions.

If you have only prophecies then you should have 6 professions available to you which are.

Prophecies.
1. Warrior
2. Ranger
3. Elementalist
4. Necromancer
5. Monk
6. Mesmer

The other 4 professions are from different chapters.

Factions.
7. Assasin
8. Ritualist

Nightfall.
9. Paragon
10. Dervish

Just make a new character from the startup screen and you will see I highly recomend you checkout those wiki pages though as they have almost every answer available regarding guild wars!

Maybe you saw a skill bar with more than 2 color schemes on it. There are a lot of PvE tracks with their own skills now (5, I guess). I could imagine a skill bar with up to 5 colors on it.
