Mystic anime Hey

one of my favourite genres of anime is a mystic one. I want to recommend you some i know and ask for your recommendations too.
Maybe the first one i saw was Mushishi (蟲師) — an outstanding series composed of 26 almost independent episodes.
The next one was Ghost Hunt (ゴーストハント) — a series of real scary ghost strories.
The other two are bought based, as it turned out to be, on novels by Kyougoku Natsuhiko (京極夏彦) — japanese mystical writer and yōkai researcher. Those were Box of Goblins (魍魎の匣) and Requiem from the Darkness (巷説百物語).

What does 貴人相逢符 mean? Just want to understand (hope this is chinese actually)

お聞かせ下さい meaning Do i get it right that the phrase "先生のご感想をお聞かせ下さい" translates to "please ask the teacher what's his thoughts"? お聞かせる here is a honorific conjugation of 聞く, but shouldn't it then be お聞かせて下さい? Or am i missing something?

春よ来い grammar Hello. If i'm right then this is translated as ”Spring, come“. However, i haven't met such a construction before. What is this form of 来る？ And what does よ mean in this context?

be- prefix Hello. Recently i've ran across different verbs with ”be“ prefix. I wonder if there's a single meaning of this prefix, so that if i know the verb without the prefix i'll have an idea what the verb with prefix is about. Examples: beget, behold, betoken, become Thanks

Currently running anime recommendations I suggest that we recommend and share our thoughts about new series which are aired or were aired recently. 

しょうがない origin? Hello, i wonder where this expression comes from and if it has a formal analogue? thanks

〜え adjective ending I think there's some tendency in a casual speech to end i-adjectives with e sounds, like かっけ instead of かっこい or すげ instead of すごい. If i'm right, what is the meaning and when is it used?

したけ meaning? Hi there. In the phrase i heard (and this is not something you should easily trust ;-) there was a word したけ which i believe is a past tense of する + け. So basically i want to ask if there's any meaning to attach け to a verb (i haven't heard about it)? However if my guess is not right, here's a phrase as i heard it is 何にめでしたけ and it's meaning is also quite obscure. If this still does not make any sense, please comment so (and i'll do something useful then maybe^^)
