Upgrading an epiphone junior.

Hi!

I got this Epiphone junior as a gift. I have other nicer and "better" guitars so I want to mess a little with this one.

I want to change the bridge, tunning knobs, pick guard and pickups. Looking into it I found that there is a possibility to include a switch like on les Paul's.

For the bridge and tunning knobs I want to go golden, but don't know any good brands.

The pickguard is the lesser of the issues. I'd like to have a white creamish look.

My biggest concern is with the guts. Pickups and the possibility of the switch. Do you recommend humbuckers or know about how to do the switch thing? I'd like them to be golden too.

Have to add that i don't want top of the line parts. The guitar doesn't really deserve a ton of money poured into it, it's more like a little project/experiment.

Any advice and recommendations are welcome.

Oh and suggestions for the volume and tone knobs! I guess white but I'm open to anything.

Sorry for the crappy english.

Edit: don't know why the photo is on its side.
