Well done so far, great change to weight and run sounds good.
For a sprint, you need to start swim and bike as you say and I´d suggest:
Swim: do you have a swim background/can you swim? If you can´t swim you´re best trying to find a GOOD TRIATHLON coach who can hopefully help you do the right things rather than learning to swim like a swimmer. You need to try to swim 3 times per week if possible - 30min per time is fine, frequency is important.
Bike: learn how to ride a bike confidenty on the road but you can do a lot of training indoors - you can use a spin bike worst case, but many gyms have Wattbikes as well. Try to bike 2-3 times/week
Run: cut it down to 2 runs per week - you have made gains in running but you need to focus on swim and bike, and the fitness you get from these will help running anyway.
Stop the 4 gym sessions (unless you have enough time to do these ON TOP of the suggested swim, bike and run sessions) - focus on doing what you need to do.
Finally, train at the right intensity - mostly easy - but build specific strength in swim, bike and run sessions (much better that doing gym strength that is non-specific and timeconsuming if you´re time limited); see:

Hope that helps
