I'd suggest looking at something like this and then modifying it to suit your situation.

First thing that jumps out at me is that you might want to look at the time you've spent on strength training since it is about the same as your running this month and more for the year. I agree it can have benefits, but if you really want to be successful at tris you have to run, bike, and swim.

Oh, and make sure stretching/yoga stays up there in priority (flexibility is important, even if just 15 min of stretching after each ride/run).

Checking out an online sprint plan (as suggested above) and modifying it to fit you is a good idea.

By modify I mostly mean just the days on which the workouts are. For example, if you can get to a pool weds and not thurs, move a thurs swim to a wednesday. In general it's a good idea to leave distances alone as you get started. Use the plan to guide how much how soon, but don't look at it as a rule book that means you have to skip a kid's soccer game! :)

And that makes sense on the strength part then.

increase training volume by 10% max each week; decrease training volume by 25% on the fourth week

you can set up your own excel sheet to calc out the progression of times. this should keep you from overtraining & hurting yourself and also predict where your volume will be X number of weeks down the road

time. it's hard to do, but focus on time and HR not speed and miles. the later will come after the former.
