My main fear is fitting g the counter tops,or joining them. My next biggest fear is screwing it up and costing us loads. I know the next advice would be to get someone in to do it,but we are really trying to save where we can.

We've been on a single wage for far too long now.
With that Bunnings kitchen in the pic it takes more time to unpack it all and read the instructions and get rid of the packaging than actually screwing up the particular carcase. Monkey see monkey do and follow the instructions. The base cabinets on their adjustable legs are set up dead level at a height that allows the kickboard to easily clip underneath ALSO allowing for the floor covering to finish underneath (who wants to cut floor tiles or edge floating floor around kickboards?)
In the case of the kitchen shown the wall cabinets were set at a height to allow those large 450mm (x 300W) high white tiles to fit between without cutting because I'm basically a lazy B and the less grout joints to clean the better (glass splashbacks anyone?)
One thing about large tiles is they're thicker and that means they'll better cover runout in walls when benchtops are all square to those square cabinets. An L shaped kitchen can be hard enough to control that sort of wall runout but with U shaped you've got 3 sides to control and allow for runout/out of square. Worst comes to worst you'll have to put a trim between benchtop and wall tiling but the art is in trying to avoid that and you can plane back laminate benchtops where flushing and plastering always leaves wall corners at greater than 90 degrees. Try that with granite, etc
You don't have to worry about fitting those benchtops together because they're all jointed ready to silicon and clamp together. The fabricator just wants those 3 wall length measurements, what edge detail where and end finishes(ie laminate finish to that laundry side end but unfinished to butt to the fridge cabinet) The art is in YOU working out what those measurements are, allowing for out of square and runout and thats all about checking diagonals for runout and allowing for planing some corners. That's where you can see U shapes present most headaches and youre doing some averaging to keep it all hidden under the tile tolerance.
Sinks come in boxes with templates for cutting out and if you stuff it up well you you just stuff it up, assuming you havent bought a double bowl sink and you've noticed a wee problem with the dishwasher fit now
