In this particular case referenced, glibness has a range of personal, meaning only the caster is affected. It has no range that extends beyond the creature who cast the spell. So if the glib creature is within the area of the globe at the time of casting, the glibness is not suppressed. If the glib creature is outside of the globe and then enters, the glibness is suppressed.

Regarding leaving and re-entering. If there is a character who can cast both globe of invulnerability and glibness, who then casts globe, leaves the area of effect, casts glibness, and then re-enters the globe, the glibness remains in effect, per the clause that "You (meaning the caster) can leave and return to the globe without penalty."

Other creatures have no exemption. So a bard ally of the wizard (or whomever) casting the globe, casts glibness (and has it active) and is within the globe at the time of its casting, leaves the globe. If the bard re-enters the globe, his glibness is then suppressed. Globe has no "memory" of spells or effects within its area, with the exemption of the caster, who can leave, cast spells, and re-enter without penalty.

EDIT: regarding "simultaneity."

In this case I believe "enter" refers to the spell's area of effect: if a spell is cast such that its effect enters the globe at the time of casting, it is suppressed. (I.e., it acts to clarify corner cases of the earlier clause "The area or effect of any such spells does not include the area of the lesser globe of invulnerability.")

The text in the SRD states:

An immobile, faintly shimmering magical sphere surrounds you and excludes all spell effects of 3rd level or lower. The area or effect of any such spells does not include the area of the lesser globe of invulnerability. Such spells fail to affect any target located within the globe. Excluded effects include spell-like abilities and spells or spell-like effects from items. However, any type of spell can be cast through or out of the magical globe. Spells of 4th level and higher are not affected by the globe, nor are spells already in effect when the globe is cast. The globe can be brought down by a targeted dispel magic spell, but not by an area dispel magic. You can leave and return to the globe without

Spells already in effect are not affected (this is explicit in the spell effects). The first three sentences refer to spell or spell-like-effects generated after the globe is cast. So a fireball spell cast into the vicinity of a globe would not affect anything inside the globe. A magic missile spell, targeting someone inside the globe, has no effect.
