Need suggestions here

As you might have guessed, I'm not expert when it comes to fitness (if you knew me in RL, you would know just how much of an understatement that really is). So, I have a tentative plan for starting out here and I need suggestions from those of you who know what you're talking about (and any level of "knowing" will trump me...so chime in!)

Here's what I'm thinking for the first couple weeks:

Monday - strength training
Tuesday - heavy bag (time yet to be determined - I want to push myself, but not kill myself and I'm honestly not sure where that line is yet)
Wednesday - off or a light walk/run to keep up the momentum
Thursday - strength training
Friday - heavy bag
Saturday - strength training
Sunday - same as Wednesday

So...my questions are, so I need to do the strength training more frequently for it to make improvements? Should I combine it and the heavy bag on the same night? Or should I do the heavy bag first rather than the strength stuff (by strength training, I'm meaning dips and push ups and things like that). Do I need those "off" nights or will that hurt more than help?

It's clearly going to be a learning process for me - to see what I am capable of and what my body will stage a revolt against. I intend to start off kind of light, but enough to push myself so I make progress. I will be finding the line between "making progress" and "hurting myself" and no one can really tell me where that line is except my own body. (I'm sure it won't hesitate to let me know!!)

For this weekend, the steps I'll be taking in the right direction are to clean out the room in the basement where my heavy bag goes and to get it set up. The ducks were in there when they stayed in the house so it looks pretty much like what you're picturing right now. So I'll be cleaning out the cedar chips and the duck poop and bleaching the concrete and then scrubbing off the nasty bleach smell with some kind of pleasant smelling cleaner. Then I'll get my heavy bag put up (with help from K, of course) and all that.

Monday will start my new life, so I need to get ready!!
