Kde look install question

[SAngeli]

Hi,

I have been using Gentoo since December and have figured out many things up to kde installed and a bit of customization. I see there is a very nice website Kde look with many items like:
- Wallpapers
- Themes / Styles
- Window Decorations
- Icons
- System Sounds
- Screensavers
- Splash Screens
- KDE Improvements
- ....

but somehow, I don't get it. It is simple to install an application when it is in portage and is not masked. When instead I see an application outside of portage I start having troubles because I fear from installing (mostly because I do not know how) it. This kde-look.org site is the classic example.

I wish to ask:
1) Wallpapers, Icons and System Sounds: I believe here I just would download what I wish and save it locally. Where is the centralized wallpaper directory I would save the downloaded files, respectively?
2) Themes / Styles, Window Decorations, Screensavers, Splash Screens, KDE Improvements: How do I install it? I guess I first have to choose the correct version of kde ( KDE 3.2 + in my case as have kde 3.2.2 ). Then, I would download the file. What is next? This is what I do not know. Also, do I have to install the Theme-Manager or not and what is needed for?
3) KDE Imporvements: Exmple is Improving KDE. How would I proceed here?
4) I see many nice desktops out there. One good example would be this
How to obtain the upper right corner data I have with gkrellm? How to obtain the weather forcast? How to get the nice taskbar at the bottom? Also, I see nice newsfeeds as trasparent to the wallpaper and many other nice stuff.
Is there a generic install approach so that once I understand the most important steps I then am able to download and install what I wish?

Sorry for this questions, but I wish once and for all solve this issue so that I can start making my kde look better. Please assist me with this so that I can learn well.

Thank you for your time and assistance in letting my learn.
Spiro
