I have the Accu-check spirit pump myself 15months now...
The infusion sets do come with different needle sizes, two different angles, 90 & 45 degree angle (the 90 degree one you can get an insertion gadet for)you can also have a d-link set, metal or Teflon needle the tubing also comes in several different lengths as well, 45cm, 60cm and 80cm's..
I use a 13mm Teflon 45 degree insfusion set, I'm pretty skinny and I self insert I don't find it a problem to do or wear.. I was using 5mm needles when I was injecting...
It sounds as though your training is going to be similar to what I did, two days with diabetic nurse and Trainer/Rep from Accu-check Rouche...
My two days went along these lines, first day got there Rep had a load of different infusion sets, straight, angled metal and teflon in all different lengths... And different lenghts of tubing as well, we discussed these had a good look at them choose the one you wanted to try..
Then given our pumps, it was like christmas as with the pump, you get a very plush black leather case to carry your spares, a plastic holder/clip for you pump, a posh leather holder/clip also another case/holder that you can either thread a belt through or hang it around your neck and a velcro strap that can be worn around the waist or thigh to hold your pump using one of the pump cases... Also a carb counting book (gem style one) we also had a postcard thing, so that we could send off for a free set of Rosmary Conelly's electric scales, which are very nice indeed...
We were shown how to set the basic settings on the pump, how to fill up the cartridges, insert the infusion sets and were up and running on live on insulin by dinner time... At the end of the first day we had arranged what time the diabetic nurse would phone us at home to check how we were doing, given a mobile number to call if we were worried about anything for the first night.. then returned the next day Which in the main was going over the aspects from the day before, and any conerns that we might have... The rep himself used an Accu-check pump so was able to give us a lot of tips..
If you give a shoot to what sort of information or concerns that you might have, I more than willing to help of I can..
good luck
