Don't Drop Your Deadlift!
Don't listen to StrongLifts' recommendation of dropping your deadlift weight by more than 50%. It's a 5x5 program with deadlifts at 1x5, so you should be dropping the weight a little bit, perhaps 20 or 25%, but definitely not from 425 to 190. You would lose strength or at least leave strength gains on the table.
With your numbers, it looks like your deadlift is great, your squat lags a little behind your bench press, and your press needs to catch up with your bench. That's fine. What I'd do is start the 5x5 progression at something like 75 or 85% of your 5RM numbers across the board. For your deadlift, that might be around 300 pounds (you don't mention your 5RM for that lift, so I'm guessing). That leaves plenty of room to improve while still challenging yourself. The same goes for your bench--it would be absurd to drop a 275 5RM bench press to 150 5x5.
Keep in mind that while you may still be a novice in the sense that you have potential to improve on a linear progression, it's necessary to modify novice programs when you have existing strength.
