I'm afraid there really are no simple ways to learn verbs at a faster pace. Honestly, I recommend picking up PRACTICE MAKES PERFECT SPANISH VERB TENSES. It's a workbook that not only teaches all conjugations, but is full of excersises to practice what the book teaches. It is about $11.00 (USD) at Borders and Barnes&Nobles. It is excellent, and I use it myself.
Most bookstores will have books on Spanish grammar. IDIOT'S GUIDE TO SPANISH is great for grammar.
I hope this helps somewhat. The resources I listed above, I have used and benefited from.
