Should Saruman have accompanied Mauhur and his "lads" ?

At the time, Saruman's forces were heavily involved in fighting the Rohirrim at the Fords of Isen, and he wouldn't have wanted to gamble by sending such a large force away from that action. Also, that might have galvanised Théoden to action despite the work of Wormtongue, and Saruman did not want Théoden mobilising the Rohirrim en masse.
Keep in mind too that Saruman did not know whether Merry and Pippin had the Ring or not.
