Hi everyone. I have a few questions first of them is: Is there a site that lists all non-standard tx's(both unconfirmed and confirmed)?

There are non-standard outputs and non-standard inputs.
List of confirmed non-standard outputs is here
http://webbtc.com/stats (Script Types: 1679 unknown)

Is there a list of all nodes that accepts non-standard tx's(at least majority of nodes)?

try these "68.168.105.168", "192.3.11.20" and connect your client to RelayNetwork
Some non-standard transactions can be pushed to network with
// https://blockchain.info/pushtx
// https://coinb.in/send-raw-transaction.html
// http://webbtc.com/relay_tx
// http://eligius.st/~wizkid057/newstats/pushtxn.php (does not work right now)
// http://btc.blockr.io/tx/push
