Add files to the bin (library); drag the desired files to the timeline and add effects, transitions, etc. Make as many timeline sequences as you like.
EXPORT an active sequence as a VIDEO FILE and give it a name (default is "untitled").
ONLY that active sequence - the one chosen by clicking its tab above the timeline - is exported.
As for rearranging, there's no need to "pull out and add back clips." Simply create a new sequence by clicking the + sign on a sequence tab above the timeline. The sequence will be blank. Then in the bin, click the SEQUENCE tab. All sequences are listed.
As instructed above, drag sequences to the timeline in the desired order. If necessary they can be rearranged on the timeline as well.
Remember, each individual sequence in the bin is a new single clip, containing all the edits/clips/effects/etc. that you edited. It cannot be deconstructed back into the original individual clips.
And, as Nat noted, the audio track may not appear in the timeline, but it's there.
