ok, i will answer this the best of my abilities:
first, fill out your profile, just so everyone can look and see exactly what you have, and where you live.
33x9.50's look good on smaller rigs, but they look kinda silly on large rigs like blazers. so, i would slap a set of 33x12.50 tires of your choice on your stock rims assuming you still have the 15x8's and just drive carefully pulling in/out of the driveway. i suggest this solely based on what you said-- you drive on the beach and want badass looks. you can also get the tires now, and add a 2-4" lift a little later. rubbing shouldnt be a MAJOR problem just drive it carefully until you can get the lift.
now, as far as lifts go, a cheap, easy way to lift it would be 2" add-a-leaves in the front and 2" blocks in the rear. i ran this set up for 4 years with no trouble, and it is really cheap (less than 100 bucks), you may even be able to use your stock shocks. this isnt the "preferred" way, but is safe and cheap. it will also give you a famaliarization(sp?-damn that looks to long/forums/images/icons/cool.gif) with your truck.
the soft top and winch w/bumper will complete the package, and you will be able to 'cruz' the biz-each and pimp the biz-itches/diz-udes (depending on your preference/forums/images/icons/cool.gif) in style!!!
good luck and have fun.......rob
