Main execution path (main thread) is going to be forked into two execution paths (two new threads on different jobs) but the main thread is no longer needed. I can assign one of the tasks to main thread and save one thread (one task by main thread and another by a new thread) but I was wondering putting main thread in an infinite sleep Thread.Sleep(Timeout.Infinite) is a good approach or not. My class is going to be instantiated many times and if a thread in infinite sleep takes resource from OS it’s bad news for me.

Each thread you create takes up stack space. On Windows, that’s 1MB by default. There are also other internal house-keeping data structures that the operating system uses to keep track of threads which will take up a bit of memory as well, but the 1MB stack is definitely going to be the biggest consumer of resources.
Having said that, if we’re only talking about 2 vs. 3 threads, then the difference is quite small. If it was 200 vs. 300 then you might have something to worry about. But if you’re spawning a lot of threads, you’d be better off using some kind of thread pool (like, say, the one built-in to the .NET framework) rather than spawning individual threads anyway.
