Clinging to Dhamma!

Is it way of Arhat, who does not cling to dhamma? By non-clinging even to dhamma, he set free? Dhammas are diad, 1) Samudaya Dhamma and 2) Nirodha Dhamma. I feel lost I think due to these: 1)view clinging: such as eternalism (e.g., "The world and self are eternal") 2)self-doctrine clinging: self-identification with self-less entities. Can only monks attain Nirvana? Have I to renounce for cessation of clinging? Please guide us. Thanks in advance!
