Project impossible? Answered

Using an Arduino UNO, an MP3 shield(and 2 speakers) and a breadboard, can I have 10 white LED's, a potentiometer to control brightness, a potentiometer to control flashing of the LED's, a stepper motor or a servo, 2 buttons for the motor(left right), and finally 3 buttons(play, stop, skip) for the mp3 plus a volume knob.

Is this possible, or will I need more that one Arduino?

Input interface: 3.5mm Stereo Jack
Input sensitivity: 650mV ± 50mV
Degree of distortion: ≤ 5%
Speaker impedance: 4ohm
Frequency range: 85Hz ~ 20kHz
SNR ≥ 80 dB
Output power: 3W * 2
Rated voltage: DC 5V /1000mA

Depends on which MP3 shield. One I used recently took all the pins on an UNO so you may need more than one or just a Mega. Also, Arduinos aren't very good at multitasking so doing it on one is going to be a feat of programming.
