To get rid of Lyra before heading to Victory Road in Pokémon SoulSilver, you need to complete a few tasks. First, make sure you have defeated the Elite Four and the Champion to unlock the ability to access Victory Road. After that, Lyra will challenge you to a battle; simply defeat her. Once you've beaten her, she won't appear again, allowing you to proceed to Victory Road.
You can find it from Route 45 and Mt. Silver. For more info click link below.
Look for a Pokemon walk through. Go to the chapter titled victory road, it should tell you how to get through, what Pokemon there are to catch, the items around that area and the trainers around that area. To get the guide try typing in " Pokemon soulsilver walk through."
It is said that Stone Edge can be found in Victory Road, where you'd find several rocks to smash and bike jumps.
Use the Squirtbottle on it, and It will attack you. This is the only chance to catch a Sudowoodo.
