well as u new to this web site idea... for ur need best is go for a Bloging script..
when u buy a cPanel hsting... it comes with "Fantastico" which allows u to install the blog in a few clicks, u dont need to know any code of DBMS whats so ever.. u can also find usesull tutorials...
later on when u get little experiance with scripting or CMS.. u may start thinking of shifting ur site to much complicated CMSes or code ur own site...
Domain name and 250MB hosting for now i guess would be fine for u... btw how many ebooks u plan to host and what are the size ??
