Using a wet tissue when making istinjaa

Q:

1. I want to know if wiping with a dry tissue then wiping with a wet tissue during istinjaa is okay before making wudu and praying because I read that using a wet tissue spreads the najasat. What if I wipe with a dry tissue first?

2. I notice sometimes that the water from the toilet seat splashes back after I flush but I am not certain if it came to me or not, so is this water najis?
