How do I delete these specific components from the system partition?

I originally partitioned my Toshiba NB205-N210 for Windows XP, so I only gave the system partition 8GB.

Recently I installed Windows 7 Ultimate (x86) and of course 8GB is too small for it to really work well. This is even if I have enabled "compress files" for C: and I've already removed everything from "Turn Windows features on or off".

I have actually been able to run Windows Update and update everything, but now it wants to install Service Pack 1, and there's not enough room - I only have 300 MB left.

When I was researching what I could delete to make more room, I came across a torrent called "Windows 7 Lite - Dark Netbook Edition". The creator wrote that he had removed these components:
---
- Projector Connectivity
- Speech Support
- Welcome Center
- TV Tuner
- NVIDIA & ATI Video Drivers
- Audio Drivers
- Printer & Scanners drivers
- Fax Drivers & Service
- Modem drivers
- Smart Card Drivers
- Bitlocker
- Tablet PC
- Natural Language
- Windows Help
- Media Center

Can someone point me as to how I would delete all this? Any help is appreciated!

Thanks

It's already installed, so it's a little late for RT Se7en Lite, I guess? Or can it be used post-installation too?

Does anyone else know how to get rid of the elements listed above AFTER installation? Thanks!

I know it's very small, but it's a netbook that I use for DJ'ing and lots of other work, so I need a lot of data on it. That's why I only allocated 8GB of 150GB for Windows XP to begin with.

So again - does anyone know how to delete these components and drivers? I only need to free up 7-800 Mb to install SP1, and then everything is fine.

Alright, so I guess I should either a) reinstall a netbook-optimized version using RT Windows 7 Lite to get rid of elements, or b) try to resize partitions. I'll try b) first with Hiren's Boot CD.

Thanks, guys!
