If by “things” you mean luminous (ca. 0.4 % of the mass–energy of the 
universe), non-luminous (ca. 3.6 %), and dark matter (ca. 23 %), then 
probably yes, because there would still be dark energy (formerly, ca. 73 %).

          ^^^^^^ :)

AIUI yes: without the positive gravitational pressure of matter as defined 
above, the negative pressure exerted on the universe by dark energy could 
quickly rip spacetime apart (Big Rip), especially if it is indeed 
quintessence in the form of phantom energy (w = p∕ρ < −1).
