Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Hooker Rory Best, who started against England last weekend, takes his place on the Ulster bench, but Andrew Trimble is unavailable after picking up a slight quad injury against England.
Paul Marshall is included at scrum half after his cameo against the Newport Gwent Dragons and Ruan Pienaar moves to out-half as a result. Conor Gaston will make his second appearance on the wing after impressing on his debut last time out.
The returning Danielli will start at full-back, taking over from Adam D'Arcy, and Wallace will join Nevin Spence at centre with youngster Luke Marshall set to miss the rest of the season.
Andi Kyriacou and Declan Fitzpatrick remain in the front row and are joined by Court. Dan Tuohy has been promoted from the replacements to partner stand-in captain Johann Muller in the second row.
The back row is reshuffled again with Pedrie Wannenburg starting at number 8, Robbie Diack moving to blindside flanker and Chris Henry at openside flanker.
The return of Ulster's international players is a timely boost as every point will count in the Magners League and the Heineken Cup quarter-final against Northampton Saints is just over two weeks' away.
Speaking ahead of the game in Glasgow, Ulster head coach Brian McLaughlin said: "If we want to make that semi-final spot in the Magners League then every game is a cup final. We have to perform in every game."
