0xA004 is the first Chibibo(Goomba).
And below is the general location for the rest of the enemies, and other non-power-up sprites for each level. Tempting as it is, you are not allowed to use fewer enemies in one level to add more to another. It's really annoying in 3-3, which uses way too few sprites.

Level Map Structure
The first byte is split in two parts. The high 4 bits are a y-component(y) and the low 4 bits are a length(x). The game draws x tiles to y + 2(because of the status bar at the top of the screen). There are x bytes following the first byte that indicate what tile to draw. I'm not sure how many bytes follow if x=0. The tile number is the byte + or - 0x80. If the byte is 0x00-0x7F, 0x80 is added. If the byte is 0x80-0xFF, 0x80 is subtracted. 7F appears to be a tile that is a used coin block. F4 appears to be a coin. An FD byte indicates that there isn't x bytes after the first byte. Instead, ONE byte follows the first byte and is repeated x times. If x=0, it fills the rest of the column. If there is a FE byte it goes to the next row. For example, at 0xA817, there are the bytes 00 FD 7F FE. y is 0. x is also 0. FD indicates there is only one tile byte. The tile indicated by 7F is repeated across the entire column because x=0. FE indicates that that is the end of the line. I'm not sure, but FF tells the game, that it is the end of the tile map. -Quoted from Coolman.

Sound Engine Commands
Music tracks are stored as a series of pointers to chains of Sound Engine Commands (SEC) for each channel. The SEC chains of each music track are stored right below their pointers.
Here is how each SEC is interpreted:
00 = SEC chain terminator
01 = plays rest
02-90 = plays note at frequency given by frequency table at 0xEF72-0xF001 (rom3:6f72-rom3:7001). Because frequencies occupy 2 bytes, only the even SECs play valid notes.
A few examples (octaves may be off by 1):
02 = C-1
10 = G-1
1A = C-2
28 = G-2
32 = C-3
3A = E-3
3C = F-3
40 = G-3
44 = A-3
48 = B-3
4A = C-4
4E = D-4
50 = D#4
52 = E-4
54 = F-4
58 = G-4
5C = A-4
62 = C-5
6E = F-5
70 = G-5
90 = B-6
91-9C = plays invalid notes
9D = set NRX sound registers (where X can be either 1, 2, 3 or 4, depending on which channel the SEC is executed for)
this SEC is followed by three bytes:
byte1 = NRX2
byte2 = NRX0? (no effect?)
byte3 = NRX1
9E-9F = plays invalid notes
AX = set Note Duration to the value of the Xth index of the Note Durations Table (where X can be any hex digit). The Note Durations Table is pointed to by ram:df01
B0-FF = plays invalid notes
