The only reason people dislike farming is because they either don't understand it or haven't tried it. It really is one of the more interesting skills. As for the worst... couldn't say. Depends on a number of factors. Some are useless & easy to train (Firemaking). Others are really cool but take much longer to train (Herblore, Slayer). So I guess it depends on personal preference. Non-PKing Combat ftw. ^_^
You can sell most logs to P2Pers for Construction/Fletching. And yes, Firemaking is the most useless F2P skill... and P2P... but hey, it's easy to train, so.
I seriously doubt I'll be thinking about RS on my death bed. And if I am, then, I wouldn't give my account to anyone - partly because I'm a strong believer in following all RS rules, and secondly because I wouldn't want anyone taking credit for my accomplishments.
It really is best to learn HTML/CSS on your own. Dreamweaver is great for assisting you... for example, getting a template or basic design down, but you should clean up the code afterwards, since any code generated by a program such as Dreamweaver/Frontpage is always very messy.
