There are alot good threads and info on this forum re nutrition and what to eat while active. If active and doing sustained exercise such as cycling, carbs, proteins and fats are essential, all at the right time. Each body is alittle different so you'll have to experiment with what works for you. It has taken me years to get the combo correct.

As to eating carbs like pasta, moderation is the key. Small bowl, add veggies to the sauce or better a piece of chicken.

Shoes: cycling shoes are like regular shoes you have to find one that works for you - can't go by price you need to go by fit. If doing short rides it probably won't matter but going over 30 - 40 miles, good shoes will save your feet. I am a fan of Sidi's - they fit my feet like a glove and I've never had any problem with them. They can be very expensive. For road shoes I like the Genius 5's they run about $239, less if on sale. Sidi does make shoes for less than $100 but buy a good pair if you can, again your feet will thank you.

Computer: depends on what you what a computer for. There is a cheap little Cateye out there that works great and records mileage, trip distance , time and speed. I think its less than $30. I'm jonesing for the New Garmin GPS system made for bicycles that run about $400. But it does everything - probably more than I'll ever need. I just want it because...

Pedals like shoes are very individual. I think good beginner pedals are either Speedplays (X2 or X3's), or SPD 939's. Once you start with a pedal you won't begin you rode with cages! You also need to decide if you want to use a road or mtn bike pedal. Difference? The Shoes. With a Mtn bike pedal you can wear a "walkaround" shoes, spmething with a recess cleat. Either SPD's or better yet, Crank Brother Egg Beaters.

Have fun. Check around on the Forum for more information - there are ots of posts on shoes, cleats etc.
