Please don't take offense... but your question has me wondering, so just to double-check: are you sure your cabinet has a tubular lock on it? (Tubular cabinet locks are rare in my experience, but they may be more common elsewhere and I'm just not aware of it.)
If it's actually a tubular lock, it's not hard to figure out whether you need a 7-pin or an 8-pin pick. If you look at the face of the lock, you should be able to see all of the pins: the number of pins that are there determine which pick you'll need. (i.e., if there are 7 pins, you'll need a 7-pin pick.)
Please keep in mind that not all tubular locks are made the same: an ACE-brand lock is going to be a challenge if it's your first lock, while generic knock-offs are often much easier. Also, it's not a great idea to pick locks that are in use: if you're not sure of what you're doing, you can leave a tubular lock in a state where a regular key would be unable to lock or unlock the lock again.
