The 1010 is a great choice of router. If you need something more powerful you can always add a 1400 or my favorite, 2200, later. In terms of other accessories, an edge guide is a must and I like the edging accessories that help convert the 1010 to something like the MFK 700, although not as elegant. I also like the LR32.
If you can still get one (it was discontinued here) there is a larger base you can buy for edge work - adds stability to to the machine and it is great for profiling edges. It is called a table widener and the part number was 493 139.There is also a similar base called an extension table that has guide rods and is part number 488 756.
In terms of bits, you cannot go wrong with Festool bits. I bought many profiles right when they were being discontinued in North America, but these are some of the best bits I have used. Very high quality. I wish Festool would bring them back to North America as I did not get 100% of the profiles I use. But, happy to have what I was able to secure.
