Infinite Afterburners
Use the afterburners to accelerate to full speed, then hold Q. If done correctly, your ship will maintain its current speed and direction until the key is released without using any afterburner energy.

Easy credits:
There is a crate filled with 1000 credits sitting between the station and an asteroid field directly below it in the Draconis Ripstar Field.. The bottom of the station is the side without te docking pad.

Hex Cheats
Using a hex editor, look for offset ...018. The hex number is set up in the standard savegame way, with two digits in pairs from lowest to higest place (i.e., if you have 6000 credits, that's 1770 in hexidecimal, and that would be laid out like this" 70 17 00" .. etc.). Then, you can overwrite this offset and modify the amount of credits you have. If you use FF FF, this translates into 65,535 credits.

If you don't want to type in the cheat code for ships, but still want to fly the ship of your choice in either campaign, use a hex editor and look for the following offsets. Then, set that offset to "01".
