Last winter I was in a similar spot mentally, gunning for it in track after (a rather lackluster, for me) xc. You're a step ahead of me with your times (I PRd at 17:15 ish). I ended up running 4:33 for the 1600 and 10:0x for the 3200. My plan was initially Lydiard and then morphed into more tinman style. I'm in college now and ran 16:5x my first 5k of the season and improved the rest of the season, but it was a very muddy year, so I didn't run too fast, but I'm in about 27 flat shape for 8k (16:2x for 5k) compared to the guys I race around. There's a lot I've learned since I made my training plan for the winter/spring this last season and from my college coaches.
1.) Be patient. You took a week off, don't rush into things you're not ready for. A good approach to come back is start at 50% of your goal mileage and add 10% of that goal mileage till you get there, take a down week, and then the next week you add workouts (the second full week). During those first 6 weeks, focus on maintaining a good cadence, even if you go really slow, so you don't teach yourself bad form, but obviously don't be doing high knees, just don't be lazy with your stride. You could plan them, or just go by how you feel each day, but during those weeks, only do progression runs for workouts. Start incredibly slow (like 10 min pace, remembering to keep a good cadence) and just naturally let yourself speed up. Every 5-15 min, you should be a little faster, but never pushing the pace down purposely. By the last 15 min you should be near LT effort (not necessarily pace). If you feel good, crank the last 3-5 min, but never tie up. These progression runs really work your patience, but remember to go by feel, don't push the pace.
2.) Strides and Hills are your friends. Do strides everyday those first few weeks, just a comfortable 4 - 6 depending on how you feel. Then do them the day before a workout and after all aerobic workouts (Easy Tempos/Progression Runs/ LT Reps). Make sure to run a good amount of your days over hilly areas, especially your long run.
3.) Take off days, but not 100% rest days. On a down week, get on the bike and go ham, get some benefit from the off day, don't waste a day to train yourself aerobically. Off days can be every week, but at least once every 3 weeks.
4.) Tinman Tempos/Marathon Pace work is amazing for you. Do these every week in base phase once you've built your mileage back up. 5 - 7 miles at this effort does wonders to your endurance. Follow with hills (whether you do hill strides or sprints or whatever). These are very similar to the Lydiard Monday, Wednesday, Friday long steady state days, which are basically 1 - 2 mi Warm Up + Steady State (Marathon Pace/Tinman Tempo).
5.) Learn to run by feel. This might be the most important one. I think this is where those progression runs help a lot too, because you really want to listen to your body on those. If you feel beat up, run a long slow run, keeping cadence up though so you're not using lazy form. Easy days can be super slow if you're beat up.
6.) DOUBLE. No, I don't mean split up your mileage so it's easier. If you're trying to hit 60 mpw, hit 60 mpw in singles, but run an EXTRA 15 min in the morning Monday through Friday. Lydiard says to do this at any mileage and I don't remember if Tinman has said this, but as long as you're not losing sleep to do it or feeling burnt out, I'm sure he would agree. These help a lot with getting aerobically fit and just feeling better in workouts once you're used to them. Don't even count these as mileage and run them as slow as you want, 9 min pace is fine. Just get out and do these. They will not make you a champion overnight, but doing these for months makes a huge difference.
You seem to have a lot figured out, but those are some big things I've learned, use what you want. If you'd like someone to look over your training plans (or make one), I'd love to, it's what I do for fun and for a few friends of mine that graduated HS and are running by themselves now.
Good luck with the next season! Make sure to ice that knee everyday till there's no pain! (Icing is fine if you hurt, don't just ice if you're sore)
