I would defo use the point motors Dave (Rammy) recommended (I used old peco ones that didnt have the aux switch... I'll use PM1's next time!!) I built my control panel out of thin ply with a Mimic type diagram produced in Microsoft paint then laminated over and stuck to the box.
For the electronics side I have followed the advice on here and, for easy reference, on brian lamberts web site http://www.brian-lambert.co.uk/Electrical.htm and his excellent book "The Newcomer's Guide to Model Railways" which is just over a tenner on Amazon now (you could maybe buy it through RMwebs Amazon book store???)
Have a look at the panel on my layout its really simple (but no LEDs). I have used buttons for my 3 way points but for normal points I just used On-Off-On switches that always return to the off setting (see my video). I would recommend a CDU to fire the points and to stop the point motors burning out by being left in the on position. I built my own CDU (about £4), again off the pages of Brian Lambert, but this was just so I could practice my soldering skills. I believe you can get a good new one for about £10.
Why not try a small mimic panel on say 4 points, thats only 4 switches, a strip of wood( no need to build a box) and a few lengths of wire that way you will get a feel for whats needed, practice your soldering and only have spent the price of a couple of pints!!
It really is satisfying when you flick a switch and your points change using nothing more than bunch of wires and switches that you have soldered together.
