There are some basic barbells there 10kg and weights for them up to about 40kg.
The dumbells only go to 32kg which is fine for now but if they become too easy to use for bench press and so on then I will run out of options.
Luckily I actually prefer dumbell bench pressing. I prefer dumbells in general.
Don't forget that you can use different techniques for maximizing strength/conditioning gains, even from weights that seem light. Ex: Flat bench press followed immediately by elevated push-ups. A benefit of having lighter weights is being forced to focus on form and muscle contraction during concentric and eccentric phases of each repetition.
I could probably subsitute kettlebells for dumbells too.
Definitely. You'll find that kettlebells are a different type of monster. The only time I suffer from DOMS (delayed onset muscle soreness)is after a powerlifting workout or kettlebells workouts. A 15lb. kettlebell can make you sore in ways a 15lb. dumbbell can't.
Any advice on suppliments too?
I used to use 90+ protein, creatine and some multi vits. Cant seem to get 90+ anymore. And all the creatine seems to have bad rep going for it.
ps. The only reason I mentioned the spotter is that at the other gym you have to have a spotter unfortunately.
Supplementation is your call based on an assessment of your diet.
Protein- A lot of personal trainers and fad dietitians say the more protein you eat the more fat you lose and muscle you gain. This is true to a point; a gram of protein does have a higher thermic effect than a carb or fat gram, and is absolutely necessary for new muscle development. However you can still get fat from over-eating protein and if you don't stimulate muscle growth your body won't build muscle. I'd say keep your protein intake to around 1 gram per pound of body weight. I'm hovering around 185 right now and consuming around 190 grams of protein per day.
Vitamins- If you're eating a healthy mix of vegetables and fruit a multi-vitamin is unnecessary. You won't hurt yourself with moderate vitamin supplementation, but you won't see a huge benefit from it either if you have a balanced diet. A basic Walmart brand multi-vitamin will work if you're dead set on adding a vitamin.
Creatine- Your call on creatine. You'll notice a moderate increase in mass largely due to an increase in water retention and muscle glycogen, and a slight increase in strength. When I'm bulking I'll try to load creatine at about 20g per day, broken into 4 doses of around 5g. Basically I'll dump a heaping tablespoon of creatine monohydrate into my mouth, take a few gulps of grape juice and swish it around, then follow with at least 24oz of water. Just as a side note basic creatine monohydrate, the cheap stuff at Vitamin Shoppe or Walmart, is just as effective or more effective than the expensive crap like Celltech or Con-Cret. My opinion speaking from trial and error.
All of the stuff I've told you is based on my own experience, so take it with a grain of salt.
