Answer 1

Your rewrite class location name is wrong.

as per as your code class is located at app/code/local/Eventprice/Meta/Block/Catalog/Product/View/Options/Type/Select but you define it as Eventprice_Meta_Catalog_Block_Product_View_Options_Type_Select

It should be

Eventprice_Meta_Block_Catalog_Product_View_Options_Type_Select.

Class is should be same with file path thus autoloader can understand it path when that file will load
