First Question:
Right now CBT#5 is running.
You need a valid Package to get your created Char to the mainworld Abella by signing in at the faryman in the Startzone.
Right now and until the EA starts in some weeks you still need one of the packages here and youll buy a valid ticket (Charslot to mainworld)
http://lifeisfeudal.com/mmo?l=buypackAdter that you just need the YO what includes a valid ticket when the EA gets started.
http://store.steampowered.com/app/290080/Life_is_Feudal_Your_Own/CBT is the Testing phase thats running right now and you need min a Package.
EA is the Phase that starts after this one in some weeks and you need min YO
After another ~2-3 Month everyone is able to go to the Starterworlds dosnt matter if you have bought the game or own a Ticket, but to talk to the Faryman that will send you to Abelle its required to have a Ticket.
Second Question:
Youre able to loot every other Player youve killed as long as he is not on a Claim. A Claim is a Zone that where you cannot loot, or destroy anything until you have War against this claim or it is your claim.
This System might change in the future to prevent RDM.
You got a Alignmentsystem that can prevent RDM and random PVP.
You need to pray every day up to 5 days a reallife day and rise your Alignment a bit (between 0.3 and 1 Alignment)
Your Alignment can rise up to 1000 and down to -1000
Every time you kill, injure or knock down an other player your alignment will drop for about 3-8 points.
If it drops lower than -50 its no turning back for your character and he will be permanently marked as a criminal.
The lower your Alignment the more Skillpoints you will loose when you die.
So Yes you can loot but not at all cirkumstances.
And You will get a bad punishement if youre playing a criminal or harm any other player.
