Evo,
A good question, well asked, but not so easy to answer.
Stalling and spinning are such complex subjects that in the test flying world there are people recognised as being specialists in the subject. The majority of people however, like you, get little chance to truly understand the subject. My congratulations on knowing your limitations, like Whirly, I had a few more hours before I learned how little I knew.
If you get a chance to experience an "interesting" spin, do - it's a very educational experience. The Bulldog is a good such aircraft, as is the C150 in certain circumstances. If possible try and fly with an ex-military, or an aerobatic pilot who REALLY understands spinning. Probably the best chap in the UK for this is David Scouller, the CFI at Old Sarum, who used to be a very senior military test pilot and has a couple of Bulldogs at his disposal for teaching aeros and spinning.
But realistically, your best bet is by reading and talking. There are a couple of good books out there about spinning, some more sensible than others. My personal bible (apart from stuff with my name on the cover, which modesty prevents me mentioning) is the spinning chapter in Darrol Stinton's unparalleled "Handling Qualities and Flight Testing of the Aeroplane". Darrol is probably the most knowledgable person in the world on the subject of small aeroplane handling, and his books are well worth the money (despite not being cheap).
Hope this helps,
