There are no tracks in Final Cut Pro X, meaning you’re not forced to target specific areas to place media. For the most part you just put things wherever you want. You can drag media into a Project, or press E to append a file, Q to connect it, W to insert, and D to overwrite (you can also perform back timed edits by holding the Shift key in combination with Q or D). Audio files are automatically placed below the Primary Storyline (the dark stripe in the timeline, generally used for building the spine of your story), video files, graphics and titles are stacked above the Primary Storyline. You can of course rearrange the stacking order at will. I suggest you read up on Roles, which add a whole new level of organizational and structural power, and are particularly useful for audio editing and mixing.

That is the Reveal in Browser command mentioned above. Select a clip in a Project and press Shift+F. This will highlight the clip in the Browser, in whatever Event it resides in.

You’re welcome! The Timeline Index is pretty darn useful. Would be cool to have an additional “Reveal Clip in Project” option in the Browser, the opposite of “Reveal in Browser”, of course.

You can look for that clip in the Clips section of the Timeline Index, or simply search for that clip using the Search bar in the Timeline Index.

Perhaps the clip C connection point is connected to one of the B clips and is thus deleted when the B clips are deleted. If you hold down COMMAND+OPTION and click on clip C (or any connected clip for that matter) you can move the connection point to the location where you click. I would try that.
