You are going about it one way: with these clothes, what bag do i need For this temp?
That is a way to do it. Another way is to start with your bag and the temperature for which it is comfortable and then add in the extra insulation from the clothes...
If i weren't sure about the clothes and was comfortable with my bag, i would start out using way number two...
There have been a lot of posts in the past about insulation ratings, clo, of clothing... You could search posts by Richard Nilsen and find these. I don't have access to the little graphs right now, but i think his tables would indicate your clothes would be about 15° extra insulation. Or there abouts. A little more if you wear both tops. I remember this estimation because i made 3 oz. Primaloft pants and, according to his scale, they should add 5 degrees. I am making a bit of a guess about your top. I used his scale as a rule of thumb. There has been variation over time in the insulation value assigned to different garments...
Anyway, I would start with the temp you use your bag and then try to add your clothes. The clothes you listed aren't very heavy and might not add a lot of warmth... They might be well considered 'extra' to deal with changes in temp, as was suggested above.
A way I tried to estimate clothing and bag was to pack clothes I thought I would be comfortable in at rest, not asleep but not working, and not in the bag... Then pack a quilt that was warm enough to keep me comfortable as my body slowed down and cooled during sleep.
That is a way I went about it... Whatever i decided doesn't matter because your conditions are different, I am sure.
PS - I don't mean to be snarky. I just mean you likely can't simply copy my choices into your use... Humidity, for instance, can make a big difference. Anyway, hope the comments about the strategies for finding your answer are helpful!
