Yes, you will be fine just installing those.
Should i risk installing them to the sysNAND im going to clone to emuNAND or just the emuNAND when i'm ready to downgrade to 2.1?

The safe way would be to install them to your emunand. The way this works is your sysnand and emunand will be exactly the same as they were before you started with the exception of A9LH.Should i risk installing them to the sysNAND im going to clone to emuNAND or just the emuNAND when i'm ready to downgrade to 2.1?

After you get your OTP you will restore your current sysnand (assuming you are on 9.2 now) and your current emunand. Then you will install A9LH and I recommend AuReiNand. Everything will work exactly as it did before but you will boot directly into emunand.
Once you overwrite the emunand to sysnand there is nothing left to "lurk". It's gone forever.
