What is the most up-to-date hastle-free way to move a wordpress MAMP site
to a webspace on 1and1.com

I've been searching for days to find the easiest, most newb-friendly set
of directions to get a wordpress 3.6 site done on MAMP to a webspace like
1and1.com, as I am a total beginner when it comes to wordpress. The
wordpress Codex I didn't find useful with regards to this issue as there
are many explanations and nothing broken down into simple, detailed, easy
to understand way. I've searched thread after thread and blog post after
blog post and most of them are not detailed enough or out of date. If
anyone would care to share their insight on their preferred methods for
moving a MAMP site to a webspace it would be greatly appreciated.
The closest one I found was:
http://www.jasonbobich.com/web-design/moving-wordpress-to-a-new-server/
but it suggests that you should use this plugin:
http://interconnectit.com/products/search-and-replace-for-wordpress-databases/
and I have no idea how to use it (they only offer a brief 3 paragraph
explanation on its usage)
Is this a good reference to go by? I just wanna make sure because it seems
like a daunting task where the smallest trace of human error ruins your
day. what would be great is something like a one-click solution (input
necessary fields like URLs and click a button that says "Move Site") but I
haven't been able to come across one that works - the Duplicator plugin
came recommended for something like this but it also came abhorred by
others so I'm a little wary on using it.
What are your thoughts? What should I do??
Thanks
