If you want to savescum, you can Save&Quit whenever you're not in a battle or asteroid field / near a sun. Then find your "continue.sav" file, which for me on Vista was in [UserName]/Documents/My Games/FasterThanLight. Make a backup copy of continue.sav, rename it to something distinctive, restart the game, and continue. When you die, go back to the folder, make a copy of your backup copy and rename that to continue.sav, and ta-da! Game restored. You can use this when you have a decision you're unsure about (like "Will this expensive weapon I found in a shop near the end help me, or be a waste of hard-earned scrap?), to make a backup at the beginning of each sector, backup right before the boss to try to hone your strategy once you have a good build, whatever. If you don't mind cheating.

(I used this method to unlock one of the ships, since I didn't quite understand how the quest worked, and the quest isn't available on every run - I didn't want to have to waste another three runs before using the slug cruiser!)
I do not have a picture, but I can remember two winning builds.
With the Kestrel Cruiser layout B on Easy, I had:
Hull Laser 2 (3 power, fires 3 lasers, moderate chance of fires or breach), Dual Lasers (1 power, 2 lasers), Heavy Laser II (3 power, 2 lasers of 2 damage each, good chance of fire or breaching), Ion Bomb.
No drones, but all other systems pretty much maxed (except I don't think I got max oxygen, medbay, cockpit, or sensors).
A full crew, including a doubly-leveled crewman manning each console (they'd been there from the start of the game) and a couple Mantis to take out the boarding drones, and to TP over to attack their weapons systems.
Strategy: Ion Bomb on repeat into their cockpit. When on hits (might take a couple tries) this eliminates the enemy's evasion. Then, fire a salvo of all lasers (Heavy Lasers fire last) at their shield room. 5 damage to shield room, they're now down to 1 shield. Kept spamming Ion Bombs into the cockpit; the Ion Bomb recharges faster than it takes for the effect to wear off, and until it does, they have 0 evasion, so it's foolproof as long as ammo lasts. Keep firing laser salvos into the shield room; when it gets destroyed you can target other systems at will.
Save cloak for when they fire their triple rockets. If you destroy the rocket gun, save it for the triple laser (or power surges on the later two stages). On the second stage, keep your warriors at home to fight boarding drones; but as soon as a boarding drone shows up far away from important systems, let it try to pound through your max-level doors while you take out the enemy ship's rockets.
When I won on Normal, I used the Stealth Cruiser, but which ship you choose doesn't matter THAT much late-game - the only real difference it makes is how many weapon/drone slots you have. Stealth Cruiser has 3 weapon slots and 2 drone slots, aka "the least slots," but it was enough.
I had Hull Laser 2 (3 power for 3 lasers, decent breach/fire chance), Dual Lasers (1 power, 2 lasers), and a Breach Bomb Mk II which was almost worthless. I also had a Drone Control with Anti-Ship Drone I and a Defense Drone Mk I.
I had max shields, max cloak, max teleporter and 2 mantis, level 5 engines or so, and at least 1 extra point in oxygen, medbay, and piloting. Didn't put many points into drone control; instead, whenever they fired rockets I paused, turned off the anti-ship drone, and turned on the defense drone. Defense drone could usually shoot down 2 rockets. Then I turned it off and turned the anti-ship one back on.
This time I made sure TP over my mantis to take out their main guns ASAP - after I'd taken out the rocket gun and the triple laser gun, it was just a matter of timing my salvos to fire at about the same time as my anti-ship drone, with the hull lasers firing last since they have a higher breach/fire chance. With the drone, my salvos were 6 shots, but with the enemy's high evasion, the shots had a decent chance of missing - but since I'd taken out their main weapons, and their remaining weapons were unable to get through my 4 shields, I could just sit there and wait until I got lucky enough to get some shots through, especially when one of my hull lasers started a fire in their shield room.
