No, a manual install is probably the best way to go at this point if you can get the tools to work for you. (extracting the firmware manually is a pain.)
However, based on your description, you're phone is crashing right when it tries to load the android image. Android itself never boots, so there's likely something wrong with those 5 files you posted there. First thing to try is re-copying them. If you're using one file copy program over SSH, try another one. (in particular, avoid WinSCP on windows like the plague.) If I remember this correctly (I don't have my tools in front of me) the files are stored in /var/iDroid on the device from iOS.
The only other files that get used during the boot sequence are the firmware files, but those usually get successfully extracted by bootlace. I don't know where they get stored off the top of my head.
Finally, there shouldn't be a need to uninstall bootlace. A manual install just basically creates all the files on the device that bootlace would normally extract for you-- it won't crash if you replace those files yourself. It *will* undo your work if you try to re-install through bootlace again, but you're safe leaving it there if you want to tinker.
