I am designing a a project to measure the protective properties of of an item from impact.

My thought is to measure deceleration both with and without the item using the Single Axis Accelerometer Breakout Board https://www.sparkfun.com/products/9332 and measure the force of the impact with Flexiforce Pressure Sensor https://www.sparkfun.com/products/8685.

Can a single Arduino Uno handle this? If so could it handle multiple accelerometers & pressure sensors to collect from multiple points? Points directly behind the point of impact and further away.

Well you can store all th data points into arrays but as AWOL said, it takes time for the analogRead to get data. So you may need a faster arduino like the new one that just came out, or you can upgrade the crystal on the arduino that you have now. It can go up to 35 MHz without problems, any more and it may not work. Also if you do that, you will have to reconfigure the bootloader.
