Well, if you want to learn polish, I wish ye luck. You'll need it
Anyway - it's good to find a tutor who will help you, because there are a lot of trouble when learning all by yourself
Polish is rather difficult language - it's based on flection (?)(you know, conjugate the verbs, declinate the nouns etc.), therefore it has a lot of exceptions and exceptions to exceptions, idioms, phrasems etc.

. Unfortunately, most of the grammar rules are really nasty.
You must, I think, learn the various endings of words, while conjugating/declinating particular word.
For starting, I think, it's good to learn vocabulary, and some basic words and later, their variants (conjugating etc.). You may look at
http://ling.pl or
http://www.leksyka.pl - these are two vocabularies, probably the best in the polish internet. The first one is completely free, you just type english word, and then click either "szukaj wszędzie" which means "search everywhere", or better - click the polish flag.
The leksyka.pl is partially free (but in my opinion much better than ling.pl), you can browse through most common words - the procedure is the same, you type in the word and then click "eng-pol" near the typing box.
Unfortunately when you'll need some specific word, e.g. militaristic or religious, the service suddenly shows you a finger and force you to pay small amount of money to browse these words (day, or seven days of subscription). As far as I know, this service is available only in Poland, through sms-system
Anyway, if you'll encounter some problems while learning polish, don't hesitate to ask me - I've studied polish philology for a few years, and as far as I'm concerned, my english isn't that bad, as I think it is
And good luck!
(in polish - "powodzenia!")
