With just four minutes played, Izaguirre laid off to Hooper on the left, who then set up Commons on the edge of the box and the midfielder struck past Anssi Jaakkola in the Kilmarnock goal.
Stokes then fired a long range shot that Jaakkola held comfortably, before Commons sent a 25-yard shot overt the crossbar as Killie struggled to get out of their own half.
Silva tested visiting keeper Fraser Forster in the 17th minute from a narrow angle on the left-hand side, but the big keeper made an instinctive save with his feet to maintain the visitors' lead.
On 18 minutes, the travelling support launched a rousing support for their manager - who wore the number 18 jersey in his playing career with the Glasgow club - following a tumultuous week for the Northern Irishman.
A scramble in the Killie goalmouth ended when Liam Kelly made a vital clearance near the half hour mark.
Moments later, Commons slid in to dispossess James Fowler then pounced on a pass from Hooper before blasting home his second of the evening from 16 yards.
Six more minutes passed and Lennon's men were three goals to the good when Hooper netted his 18th goal of the season, collecting from Stokes, before sidestepping Pascali and rifling in from the edge of the penalty area.
Shortly after the restart, Stokes contrived to miss from two yards out after Hooper had crossed in from the right, then Commons struck the underside of the Killie crossbar.
The onslaught continued when Stokes shaved the top of the Killie goal with a powerful shot from wide on the left.
As the hour mark approached, Mulgrew sent a long ball forward for Hooper to cut back from the edge of the Killie penalty area, then Stokes sent his shot straight into the back of the net from 10 yards out to increase the lead to four.
Jamie Hamill rolled a side-footed effort straight at Forster after breaking free of the Celtic defence, but the big keeper was unfazed.
A patient build-up handed Mark Wilson a rare shot at goal, but his long-range effort inched wide of the mark, then Hooper had a shot from 10 yards tipped over the Killie bar by Jaakkola after Silva had put Forster under pressure at the away end.
A cheeky chip from Georgios Samaras in the final 10 minutes of the match failed to catch the Killie keeper off-guard, then Kieran Agard was bundled off the ball in the Celtic penalty area after breaking loose with two defenders to beat.
An injury-time free-kick for the hosts was easily headed clear by Mulgrew and Celtic held on for a clean sheet and three precious points.
