Where should a newbie like me start?

Hello world!
I've always had an interest in online marketing but I never knew where to start, but thanks to the great threads on here I now have some info about IM. Here's what I know:

-I need to find my own niche, and then build or buy a product
-I need to have an attractive sales page for the product
-I need to promote my product/website (on-site & off-sit SEO optimization, backlink building, enail marketing, article writing, social bookmarks, feeds) let me know if there's anything else.

Here's the catch: I know what to do, but I don't know how to do it!!
there are too many ebooks on here to buy that promise you tons of $ in 1 week which actually makes it hard for me to believe them because I know for a fact I have to work for it and there's no easy way to do it. Can you guys teach me something that works or point me in the right direction?

..One more thing, when I first joined this this forum I bought a niche blog from gorgeousnicheblogs.com (Blogging Niche Package), it's a nice package that comes with a squeeze page with a report, a minisite with an ebook to sell, and video tutorial bonus. I will post the website when I finish editing all the pages.

My questions:
-was buying this blog package a good investment?
-will I be able to sell the ebook that came with it (since it's PLR would you guys consider buying it or you just buy original stuff)?
-how would you market this blog to sell the product if it was you?

and my last question would be, whats the next best thing to niche blogs if there's any?


Wow that's a lot of questions to annoy the hell out of anybody, I would understand if nobody replies lol
