Looking for some geared campag advice

If all these questions have been asked apologies please put me in the direction of where I should look.

Basically Ive been meaning to put my bike back to Campag record for ages and gonna do it now but buying everything separate off ebay means Im not quite sure what goes together.

(these questions will be slight basic Im expecting apologies)

1) The first question is how can I tell what campag rear derailleur is 6 / 7 / 8 / 9 speed? There are a lot of nuovo records, c records, super records about but I've no idea what speed any are.

2) Are different down tube shifters needed for different speeds?

3) Does the front derailleur have anything to do with rear derailleur speeds? Can I just buy any front mech if I have two front speeds?

4) If I have a vento wheel with 10 speed can I switch it to 9 speed without changing the freewheel?

5) If I switch the the front and rear derailleur from shimano to campag I know I need to change the rear cassette but would I need to change my two front chainrings also?

6) If I did need to change my chainrings how do I know the amount of teeth I need on the new ones? What does that need to be in accordance with? Do I need to worry about the bottom bracket?

7) And if I wanted to put record cranks on it how do I determine the size and again do I need to worry about the bottom bracket.

8) Finally I want to get a respray where would you guys go?

(the bike is a 70s/80s gios by the way)

If anyone is able to help it would be much appreciated, so in advance thank you very much.

So many questions...

Go to a bike shop. Buy a Pinarello. That's what most people in your boat seem to do...

radical idea there^^ like it.

I'm using 80s Super Record cranks, mechs and friction shifters with Campag 9-speed wheels with no issues.

It gets more complicated when you go indexed.

What era Campag do you want to run on the Gios?

here we go...

1) http://www.sheldonbrown.com/speeds.html, for help identifying components have a look at velobase, they have alot of campagnolo catalogues

2) http://www.sheldonbrown.com/speeds.html, and yes presuming you want indexed shifting although if your thinking of 9 speed, you probably don't want downtube shifters (unless your mad).

3) It has a very small amount to do with it, the more gears you have the more crossed your chain can become. This requires a slightly larger derailluer cage to stop chain rub but is not an issue if you have enough trim (campag does)

4) A 10 speed will have a cassette not a freewheel and yes they are interchangable (but not to 8 speed and below)

5) no

6) ...

7) Determine the size? Length of cranks and number of teeth is entirely up to you. Your bottom bracket should match the cranks though, 102mm BB for 1995 record onwards, 111mm BB for C-Record...

8) Lots of thread on this...

Good Luck...

thank you so much for this advice, really kind of you, exactly what i needed.

(in answer to the questions, ill probably keep it seven speed with downtube shifters, Im not really sure what era campag I was looking to run, maybe now Ive decided to keep it seven speed the last of the seven speed derailleurs? and as for buying a pinarello, I love my bike too much for that, and my pockets are not deep at all)
