For conjugations of verbs into all tenses, use: http://www.123teachme.com/
You can just type the verb into the search box at the top right side of the page and hit enter, et voila - a list of proper verb forms in all tenses (but you have to know the Spanish word first)! I have actually just saved the PDF versions for the most common ones to my PC so I can print them one of these days and have them tucked into my purse for when I am standing in line at the bank or some such occasion - I hate wasting time!
For help with pronunciation, also don't forget that Google translate has the "listen" button. And for everything, you can use YouTube as well. I used YT a LOT earlier this year to brush up on my long lost high school French when I was tutoring my neighbor's teenage daughter. I found it truly awesome how easy it is now to learn or re-learn. languages!
By the way, if you don't have one yet for your purse: a really good dictionary is the Larousse Pocket dictionary, available at most any Arrocha for around $5.00 in the stationary department, and it is the red one.
