In jazz chords (such as 7ths, 9ths 11ths..) what notes may be ommited without ch!
Question: There are really only three essential tones to form the chords you describe above: the third, seventh, and whatever else is altered or added to the chord (such as a 9th, 11th or 13th.)
The root can be omitted (as the bass player will typically be playing it)- although you may keep the root if you are playing solo. The fifth is almost always omitted (unless it is an altered fifth, like #5), and you don't need to stack thirds on top to create the added sonorities (so if you are playing a 13th chord, you don't need the 9th or 11th.)
But don't worry if you play one of the "omitted" notes- there are lots of great guitar voicings that sound fine with the fifth (or some other non-essential tone) played.
PS: Here are two easy formulas for playing 13th chords:
For G13 (3rd fret Barre chord):
G on the E string
D on the A string
F on the D string
B on the G string
E in the B string
G on the E string
For C13 (3rd fret, partial Barre chord):
E string muted
C on the A string
E on the D string
Bb on the G string
D on the B string
A on the E string
These can be easily transposed up and down different frets.

Really any of them. Whatever works will work. It depends on context, what notes may be sounded by others, the size of your hands, the duration, etc.
There are a few quasi-rules, for example, don't play the root when playing ninth chords, but in the end it's whatever sounds good.
