Please Help: Formating in Blogspot Sucks!!!!

I dont know if I am the only one facing this problem or is it that I am too dumb to solve this formating problem in blogspot? I changed my template thrice if its a template centric problem but it isnt. Firstly, whenever I try to write in seperate paragraphs, I find it almost impossible to give double space between two paras. How many times I try to give two spaces, in the final blog, it comes the same. Many a times, it is not even a single space. It looks really ugly to see the content loose its punch because of poor formating. And then, when I try to write the blog in sub paragraphs with indents and tab spaces as we do it a word document, the sub paras never appear, even if I create one using blank spaces and push it a little right. The crib about the spell check is the worst one. Try using the spell check and when I indeed substitute with the suggested spelling, something wierd happens and only a part of the word is replaced with the new spelling, with the rest cling still hanging on, making it all the more wrong.

How to underline a particular word? Is there a way? Can one use colours other than what is given here simply by changing the colour code in HTML edit? In anycase, I am totally clueless about HTML and all the changes I have made is infact through logical comparison and amending another code of a similar nature and pasting it. Is there a way to use smilies in posts? The photo upload feature isnt working at all!! The page always loads with errors. When I click "upload" it says "Error on Page"!!

So many problems in blogspot. Someone please help!! Are koi sunte ho? Yaravathu udavi panungo!!
