I've done some research on them individually, but I'm wondering if they could be connected?

2004 Freelander HSE, 93k miles, its having problems accelerating and sputters around 30 and 50 mph. Service engine soon light comes on and off.

P-codes:
0171
1319
1472
1475
1477

I'm a college kid, pretty handy, and my dad knows a decent amount about cars. Are these something we could handle ourselves? Thanks guys!
