hi, welcome to the forum !!!
gmatclub.com is a unique community of test takers and scholars from all around the world sharing their GMAT experience. everybody contributes with his or hers experiences/strategies/comments etc - thats the thing that makes this forum so great. anyway to anwer you quesiton - yest there are a lot of first timers out there who will take their first GMAT in Q1 of 2005. i am planning on doing it in late april or early may. i am targeting a high score 700 + and i have all books that you mentioned. i also bought princeton review's cracking the gmat 2005 + cd and the 2 workbooks from amazon.com ; i read great reviews about the products offered from princeton review. i am considering buying the arco math workbook as well. I started with kaplan and i am continuing with the OG next month, after that PR, ARCo and so on. until i ran out of books and materials to work. as far as online test go, there are some on this website , also check out some auctions on ebay, sometimes they have official tests from ets for $10 or less for 9-10 of them [these tests usually retail for about $25 for 3, you can see the savings on ebay] ; try problems on this forum, they can be a great practice tool, also some of the advice you'll get here you cant get in any book - some of these guys here are just genius; try also old paperbased tests from old editions, but remember to factor the time difference in the old format and convert it to the new CAT format which is 2.5 hrs not 3 as it was on the old paperbased. hope that helps, good luck with your prep.
