Q1: says your main class is an Archer. you shouldn't use any MP unless yorui playing songs, which you wont get until your a bard. TP will be your only drain.

Q2: Houses are not being released until the big Patch later this year. info on that will then be given out.

Q3: quickest way to lvl. Main scenario quests/FATES/side quests. Especially prior to lvl 35...atleast IMO - I didn't join a FATE group until lvl49. didn't see the need...unless you want to rush to lvl50. still only took me 3-4 weeks of playing to get lvl50 - and I still have a 9-5 job.

Q4: learn crafting when you want...that's what I did. really didn't get into it until I was lvl50 on my main.

Q5: lots of Dungeons, hunting log, etc. pretty much everything you mentioned. a lot of the fun stuff comes after the end games quests. play around with different classes/crafting etc. plsu more will be added in upcoming patches

other than that, have fun and make friends. join a guild.
