As has been suggested, I would definitely NOT suggest this style tent to a beginner camper, as they can be somewhat tricky to set up...once you know how to do it, it isn't bad, but is almost impossible to set up correctly with just one person.
I'd definitely suggest you look for a bigger dome-style tent, we use a pretty great tent we got at Costco up here in Canada that was IIIRC about $100 CAD when we bought it a few years ago. I'm kind of a tent snob, but am shocked that it has lasted these years and has been one of the most popular tents we have. it has a rather big 10x10 floor area for the main tent (which sleeps the four of us quite roomily) and still leaves an outer "vestibule" area that is about the same size outside as well. Butt simple to set up, I can do it by myself with ease...and is so easy that my 5 and 8 year old daughters actually have a good time helping Dad set it up. Take down is also a breeze as well.
The in-laws also got a pretty nice tent at Wal-Mart as well that is a similar idea, but without the larger vestibule in the front, but still with a fairly large floor inside. And for car camping they work reasonably well, I've also used them for some backcountry canoe trips we've been on well enough.
it has been a while since I've set up a tent like yours...and they are generally a PITA to set up, but once you get the hang of it aren't too bad and actually stand up fairly well to wind and weather abuse. Keep in mind though that you really do need level ground to set one of these up, if the tent pad area is at all not level it makes it darn near impossible to tension the tent properly to get it to stay set up.
What I usually did to set ours up was to lay the tent out and stake down the two end corners, then pull the floor of the enclosed tent area down and stake those corners down as well. I wouldn't worry about the screened porch much at all, and worried about that once the tent portion was up.
Get all the poles put through the loops, and lay them all down on the tent side of the tent. Pick up all the poles at once and hold them all up at the middle pole, it should always stand straight up, 90 degrees from the ground. Get someone to hold that middle pole, and then gently "drop" the rear pole down, pulling it back and creating tension between it and the middle pole. Once you have created a suitable tension, peg down your guy lines (the ropes for the tent) and if done well you SHOULD be able to let go of the middle tent pole... but don't
Angle the front pole out, this is the point that I'd get that tensioned properly, then peg down the front screen corners, and if you have front guy lines, get those done up then as well. At this point the tent should be up and standing by itself, you might need to do minor adjusting with the poles to get everything standing well enough, but that should be it. Once done, then go around the tent and stake out the rest of the peg loops and get the rest of the guy lines down.
Good luck with whichever route you choose.

). We have used the instat tent twice with no leaks in bad weather, I did have a little water around the zipper but it was cleaned up with a tissue. Ease of use speaks volumes when traveling with the young'ens. NOW the insta tent is not practical for back pack camping, it's way to big to carry a long distance, but it's perfect for popping out of your trunk at the Fort
