I am a PC user ....Windows

Windows movie maker will do just fine for you op and it's already in your system if your using Windows

Yeah, or Pinnacle if you want to increase coolness.

Looks like a good place to start. [link to www.pcmag.com]

Yes, windows does have a nice video editor already installed...

...for professional editing I use "Final Cut"

The downloaded video files from Youtube are generally in FLV format (Flash Video) which is an Adobe standard for video compression. It has fast becoming the web standard for delivering online video (replacing Apple QuickTime, AVI, Windows Media and Real rm formats) because Flash Video can be viewed inside Macromedia Flash Players which is shipped by default with most web browsers.

The most common question among video enthusiasts - how to split a large FLV video file into smaller chunks for editing or resharing only the interesting tidbits on the internet. To break an FLV file, get the free FLV Parser - a tiny command-line tool to split FLVs into pieces. Its intended use is to convert a large FLV into a series of shorter FLVs based on a series of millisecond-based timecodes. Using the -s switch will split the audio and video of the outputted files; the audio track will be extracted as a series of MP3 files, and the short FLVs produced will have no audio track at all.

The free Simplified Universal Player Encoder & Renderer software from Super can convert FLV files to practically any other video format including MP4, MOV H.264, AVI, ASF or Flash SWF animations.

Say you complete editing your movie in Windows Movie Maker or VirtualDub [link to prdownloads.sourceforge.net] and now left with an AVI file that you want to convert to FLV. Just get the free Riva FLV encoder and relax. The Riva encoder even lets you select parts of the video that you want to convert to FLV and crop the rest.

I am not aware of any free software that let you join FLV files other than the expensive Macromedia Flash Professional. However, here's a simple workaround to join several flv video file - convert individual flv files to avi using Super [mentioned above], then join the multiple Avi files into a single avi file using free VirtualDub and finally convert this avi back to FLV using Riya FLV encoder.
