Few questions ... don't really know where to post this..

Alright I just have a question but i'd like to state something before I start 1. I am not a noobie 2. please do not under estimate me just because of my age 3. i'd appreciate it if you weren't ignorant, rude, an all that stuff thank you =)

I was just wonderin/thinking about this things here I go =)

I've been designing templates for a while but my problem is what type of coding should you go with once you've finished your design, I love designing websites/template but i don't code them because i have no clue on what i should do CSS, DIV LAYER, IFRAME, TABLES, I'm skilled with all of them not that much in CSS but im learning but i was wondering how do you guys go about coding your site i mean making your choice.

OH yeah do you guys hand code or are there some programs to help you do this i have dreamweaver but i duno of any other programs
