OK so I've been working on this problem for 4 days straight now, and I almost nailed it completely. So far I was able to get Plymouth to boot with messages displayed, but unfortunately the messages are truncated. Right now am trying to tweak the scripts but i don't know where the problem is in the /lib/lsb/init-functions script or the /lib/plymouth/themes/"theme-name"/mdv.script.
Here is my work so far.
first you have to make init-functions send messages to Plymouth by making it look like this (go through each line to see the differences and copy the line which corresponds to Plymouth sending):
# /lib/lsb/init-functions for Debian -*- shell-script -*-

Basically the script can be applied to any theme, all you have to do is provide the filenames of the images in the folder. And changing a few other lines to adjust the images on the screen. Or what you do is you copy the necessary part like the lets say you want the progress part so all you have to do is copy everything from
----------------------------------------- Progress Bar --------------------------------
till
----------------------------------------- Status Update --------------------------------
After you are done with editing the mdv.script be sure to sudo update-initramfs -u
and on your next boot you shall see your new splash.
Be sure to check out the links provided in my question they are very informative and will get you to understand plymouth scripting in no time.
Now if you have done everything i said here you boot splash should display scrolling messages. Now about the truncating part, I am currently working on it, but its kinda annoying to have to reboot my machine everytime i make some change. Is it possible to test a boot process while am logged in like
sudo plymouthd ; sudo plymouth --show-splash ; sudo plymouth update --status="Hello" ; sleep 2 ; sudo plymouth update --status="This is a test. This is a test. This is a test. This is a test. This is a test. This is a test. " ; sleep 10 ; sudo killall plymouthd
Another way you can test Plymouth is by copying the above command into a text file and adding sudo plymouth update --status="your message"
to have more messages scroll through. Then make the file executable and run in terminal.
Hope this helps anyone else wanting to edit their Plymouth splash. Good Luck!!!

Install Theme
I have created theme as you wanted with a faded Ubuntu logo (moreover I have added an animation of the Ubuntu logo. Hope you'd like it :-P )
Screenshot
Want to see it live?
Go to http://www.youtube.com/watch?v=zPo50gM3txU
Where can you get this theme?
I have uploaded it to Mediafire cloud here.
How do you install it?
Download from the above link, save it on your Desktop, then issue these commands one by one. Please replace
/lib/plymouth/themes

How to create a Plymouth theme yourself
Plymouth Scripting Language is very similar to C or JavaScript. If you know these languages, it'll be very easy to create Plymouth scripts yourself.
Let's start with basics like operators, looping, comments, etc. Three type of comments are supported.
Statements are terminated with a semicolon, e.g.
Statement blocks can be created with curly brackets, e.g.
The supported operators are
+
,-
,*
,/
,%
. Shorthand assignment operators are also supported+=, -=, *=,

&&
,||
,!
