When playing rubber bridge, my partner and I play a very simple system. It is a fairly sound opening version of Standard American, but we modify it to be much more aggressive when we have a leg on.

1♣/1♦ = 13-21, 3+
1♥1♠ = 13-21, 5+
1N = 16-18 balanced (13-18 with a 60+ leg on)
2♣ = 22+ points
2♦ = 8-12, 6+ (5+ with a 60+ leg on)
2♥/2♠ = 8-12, 6+ (5+ with a 40+ leg on)
2N = 21-22 balanced

The only conventions we use are Stayman and Jacoby transfers (both off when we have a 60+ leg on), splinters, and Blackwood. To show slam interest with a leg on, a voluntary jump past game is used (so with a 40 leg on, 1♥-3♥ would show slam interest), and a double jump past game is forcing to a small slam and thinking about a grand (so with a 40 leg on, 1♥-4♥ would be forcing to 6♥ and thinking about 7♥).

Two questions: (1) Are these modifications with a leg on wise? (2) Is there a good source of information on rubber bridge bidding?

Really the better question is whether these methods are working for you. You could perhaps put slam force hands into hands with slaminterest and make your double-jumps past game show more specific hands.

Most rubber bridge clubs will have their convention rules available. Your club is much more liberal than usual.

It's pretty standard that any unforced bid beyond completing the partial implies slam interest. In a competitive auction, I'd suggest that a cue bid would serve this purpose, since jumps should be preemptive.
