I would bunch those plants together a bit tighter. It will give the fry more hiding spots. The filter intake, I would cover it a prefilter sponge or some NEW cheap pantyhose. This will stop the fry being sucked up until you catch them. Keep the other fish well feed, this can help prevent/reduce the others from eating the fry but as your still cycling, keep a very close on your water as this can cause Ammonia increases.
Your priority really should be to get the tank cycled above all else. If you really want to save this batch, then go for it but just be prepared to do even more water changes than your doing at the moment. Personally I wouldn't try and save the fry but it's your tank, so your call. Good luck with it though....
