You, in all probabilty have either bad battery connections, a bad battery or the start solenoid. I would say the connections are the problem.
Change the fuel filter.
98 Nissan sentra only came with ga16de and sr20de, any ve motor would be considered a swap seeing that its a motor made strictly only in japan
No, but it can be replaced. I would recommend taking to a professional.
depends on where the oil leak is at
crank sensor bad, MAF sensor bad, dirty throttle body, idle air control valve
Start with checking the battery terminals for corrosion, then the wires going to the starter. Be sure everything is clean and tight. Also have the battery checked
It would depend on your level of competence.
Leak or blown gasket.
