Answer 1

to get to world 7 you have to beat the boss on world 2 as mini mario. it is the same as how you unlock world 4.

www.vgstrategies.about.com/od/nintendo...

That site tells you about the warp cannons :-)

Answer 2

to get to 7-A:

go to stage 7-5. store a mega mushroom (mega mario smashes blocks to find the exit)

close to the end of the level, you should see:

pile of brown blocks between 2 orange pipes.

now it's time to break those blocks (they are above a hidden green pipe).

use your mega mushroom and smash all of them.

go through the green pipe, and the next one. go to the red flag and you finished it.

i'll show the warp cannon for world 1:

first he'll show you the normal exit (tower), and then the secret exit to the cannon.
