It is hard to guide someone really... as really the amount of work can be small, if just want to change position of one sentance... but very big if you want to match a new design layout you have come up with.

Basically the mods effecting layout of pages will help you in correcting one or two sentances.
So think which page you want to change and then look for mods on e.g. Category page and use those as a guide (just remember to save a copy of each php or tpl file before you ammend it on your server... so you can replace it, if you make a mistake)..
In V4.2.0 I also understand position is controlled by CSS style file a large amount - so you can move things easier using CSS placement (get a CSS editing free software and you can view this file easier).

In regards to using two skins, their is a skin switching module from BSCE mods - I have not used it, but understand you can have another skin folder (e.g. skin1 and skin2 folder)... ask them questions on that if you like (i.e. is it the whole skin folder that it uses and can a language be set to a certain skin using it).

Otherwise I could recommend a programmer could help you do (and shouldn't cost too much). PM me if want a contact for that...

But honestly, it is generally not a small task to move things around (if you know php and CSS well, it is not that difficult, but takes time.. but if you do not know those, then it is not a small task).
