welcome, you can get some good advice on here there are three tubers on here who are usually quite helpful.
Valves are relatively easy to replace but be careful not to drop the inside bit in the toob.
The toob must be scrupulously clean and it's going to be too cold to stick anything at the moment. so do it in you garage which you could heat ar find a warm indoor place.
post some pics of the Damage and that will help.
To those who have been around RIBS for some time It's quite Ironic that a Tornado has split toobs.
Don't read anything into that at all they are good well made boats
