Can someone tell me in plan and simple terms what some of the more important features and options are for gcc and what they do? I look at the man pages and my head feels like exploding lol.

A:
You might want to read the manual on gcc options, that groups the options in meaningful ways, and includes precise descriptions of same.

Good question, and it really does have an answer.
-Wall
gcc -Wall ... will add lots of useful warnings to make C a much safer language to program in.
Regarding the comments, sure, I like -Wall -Wno-parentheses and various other variations.
But someone starting out has to, well, start somewhere.

It also adds a lot of useless ones that hide the real problems. I find if I use -Wall I generally need 5-10 -Wno-... options to get rid of the spam.

@R: not in my experience.

A:
-O flag with a numeric value will tell the compiler which level of optimization to use when compiling
-pedantic will make sure your code is iso compliant
-o To specify the name of the target executable to generate (by default it's a.out)
-Wextra to add additional compiler warnings to -Wall

You may want to check out http://tigcc.ticalc.org/doc/comopts.html
As others pointed out: If you are running some sort of unix you can usualy just write 'man gcc' (without quotes)
