I use a variety of programs depending on what I am trying to achieve and how hard I want to work with it. You can install any of them from Software Center or using apt-get
Audacity - Simple recording and editing. If you are doing a couple of tracks and generating stereo output, this will work.
Rosegarden - This is my bread and butter when I come down to working with MIDI files and doing sequencing. I use a MIDI keyboard for entry, QSynth (fluidsynth) as the playback MIDI device(s), and Rosegarden to do the capture and editing of the MIDI. It also supports capturing and playing back audio along with the MIDI, as well as the production of sheet music from the MIDI, but it is not what I would call a real digital audio mixing console.
Rosegarden uses JackD.
Ardour - When I want to delve into the word of digital audio (re)mixing, this is what I reach for. Multi-channel, multi-bus, supports per-channel digital effects plugins, and has a bit of a learning curve. IMHO, it compares well with Pro-Tools(tm), but I have only seen pro-tools used and found I could do the same with Ardour. One session I did with this ended with 5.2 mix down with separate L/R/C front, L/R rear, and sub channels. The original source was recorded from playback Rosegarden (I told you I used all of these for different things!) and then mixed.
Ardour uses JackD.
Pulse Audio
[Warning, this is pure opinion and rant....]Pulse audio and any serious sound work do no mix. I don't do serious sound work, but I run 3 sounds cards in my machine. I had them running very well under ALSA (yes, it took a bit of work). When Ubuntu shoved Pulse Audio down my throat, I spent several long nights trying to get things happy again and get the right sound card mapped to the right place. I then finally uninstalled Pulse Audio, and reverted to my ALSA setup and could get things going again. YMMV
Recent Picasa version (maybe also thew older ones, not 100% sure) are using the Quicktime codecs to handle .mov files. That means that if you do not have the plugin installed in your system Picasa wont be able to do anything to those.
Because Ubuntu comes with support for .mov files via GStreamer but that does not mean Wine will take advantage of what Ubuntu can do. They are separate systems.
That means you need to install some sort of codec support to be able to play .mov files inside your Wine system that includes Picasa. For that I recommend to try either any Windows plugin pack that has .mov files or a lite Quicktime alternative (the standard player wont install).
For a plugin pack with .mov support I can recommend the K-Lite Codec Pack since it is know to install and work under Wine and for a Quicktime alternative I recommend QT Lite which is a lite QuickTime implementation.
After you installed any of these 2 inside the same bottle that contains your Picasa install the .mov files will then be supported by Picasa.

There are a number video transcoders that you could use to covert mov files to different formats suitable for uploading. Handbrake is a popular one that has both a GUI and command-line version (
handbrake-gtk
orhandbrake-cli
). To use Handbreak on Ubuntu, you need to add a PPA:https://edge.launchpad.net/~handbrake-ubuntu/+archive/ppa or the more current https://launchpad.net/~stebbins/+archive/ubuntu/handbrake-releases
I personally like, transmageddon which is a GUI app with nice simple pre-sets. It's available in the archives.
Another option is arista, another GUI transcoder available in the archives. In fact, it is a "Featured Application" in Ubuntu Software Center.
ffmpeg
is another command line option that offers a lot of flexibility but can be a bit complex.
