You can place flowers on dirt blocks or make a garden out of them. In minecraft 1.4 (which is coming out in october or november) they'll have flower pots which will be really cool!
Blue flowers can only be found when playing with mods or playing Minecraft: Pocket edition.
there are yellow flowers in the game, so use them. Wikipedia it if you still are unable to figure it out.
You cannot get grass seeds in Minecraft. However if you want to plant some along with some flowers you can use bonemeal on some dirt/grass and it will grow.
