Question before purchase.

i want to purchase xenforo. But, im from slovakia, and i need slovak language.I tried demo, its very nice:) , but, when i changed language from EN to slovak as default, nothing changed. (forum was not translated)

That means, i need to translate every phrase one by one from english to slovak? or i can use google translator online or is there any tool i can use?

My second Q is:
where i can purchase realy nice forum skins?

My third Q is:
can i use XF on shared hosting? i had vbulletin on VPS server, but i almost bancrupted heh:) so im wondering if XF is also sql demand as vbulletin.

thank you!
