-No difference in techniquie for brewing a wheat vs non wheat ale (I'm assuming you are doing extract?)
-AUstin HomeBrew Supply has a HUGE supply of awesome kits. You can probably find somebody who has brewed all of them on this forum for specific reviews.
-For dry vs liquid yeasts, it depends on what style beer you want to make. If you are going wheat or Belgian, I would recommend a liquid. If you are making anything else, I would say go with a reputable dry yeast for your first batch.
Good luck and welcome aboard!
