As you can read here...
http://www.atmel.com/devices/atmega2560.aspx
...the '2560 comes w/ JTAG debugging interface.
The Arduino board you mentioned...
http://arduino.cc/en/uploads/Main/arduino-mega2560_R3-schematic.pdf
... lets you access the JTAG pins via the ADCL(provides TDI, TDO, TMS,
TCK) and POWER(provides SRST, GND) pin headers, respectively. TRST is
not needed, according to the '2560s data sheet.
For debugging this processor you will need an parallel port and an
parallel port to JTAG adapter or an Atmel USB debug adapter like the
Atmel Dragon or an JTAG-ICE II/III. Even with open-source debugging
software on PC side only Atmel or other commercially sold debuggers can
be used. The FTDIs don't work afaik.

At the LinkSprite product page...
http://www.linksprite.com/product/showproduct.php?lang=en&id=86
... is stated " It can be used in GCC+Eclipse+openocd+openJtag and
Arduino enviroment! ", which means, a cheap FTDI JTAG adapter will work.
I will leave the decision which board to use up to you, since i don't
know how much experience you have with the one or the other processor
families and i don't know anythig about how much "numbercrunching
power", RAM and built-in features as ADC, PWM... your specific project
will need.
