Johnson, Guinan and Jacobs scored the goals at the New Lawn as Forest Green Rovers were brushed aside in the FA Cup.
Boss Ian Sampson has now seen his side pull off two excellent league victories and book a place in the second round of football's most famous competition over the past seven days to considerably ease the pressure on his position.
He told the official club wesbite afterwards: 'The attitude of the players was spot on from the start and the first goal really settled us down'.
The draw for the next round takes place on Sunday, live on ITV following the Southport versus Sheffield Wednesday clash.
Second Round ties are to be played on the weekend of 27 and 28 November 2010.
